I have multiple items that were previously approved by Google but my Shopify dashboard now says I must add a GTIN or MPN. I have already input the GTINs, that is why the products were able to be authorised in the first place.
Does anyone have any advice on what I have to do?
Iām having this issue too - there was another discussion about this and I posted this reply - "all my products have GTINs and everything is set up correct, however, my Shopify page and my Google Merchant account are now showing over half my products are not published due to GTIN missing??
I spoke with Shopify support and they told me they hadnāt had anyone else report this -however, the guy I spoke to went through my account and couldnāt find any āmistakesā so he has 'escalated my support ticket to the technical team.
According to him there appears to be a syncing error between Shopify and Google Merchant - but he couldnāt tell me what this issue was yet. He said the technical team would need to look at it further. I am actually kind of happy others are experiencing this too as this should mean that Shopify will make it a priority to get it sorted".
Is this the same issue you are having?
yes sounds like the same issue!
Mine we fine before but recently changed, were yours okay previously too?
This is a terrible time for this to happen to us too, hope it gets sorted quickly.
this is concerning you say there is no one else who has registered this issue. I have multiple times.
For some reason shopify isnāt talking to merchant centre.
I bet if you go into the Shopify channel app and select all your products, then hit edit you will see under the ācustom_idā, the first column, you will see many blank squares. you need to choose either true or false (depending on whether you have a GTIN or not and then I bet it will appear in merchant centre within 24 hours
I havenāt heard back from Shopify yet regarding this but I did just have a long conversation with Google. They have confirmed my products are all set up fine and have suggested for each product I select āsubmit for Manual Reviewā - you can find this halfway down the page on each individual product under the Diagnostics tab in Google Merchant.
They said after this they should all be āapprovedā within 3-5 business days.
Google told me it is actually just a āwarningā and it may be part of their process of weeding out fraudulent products. They assured me all my products are still showing in Google and in shopping ads.
Sorry I meant to say there āareā other people reporting this (not arenāt 
) I just spoke to Google Merchant - see my comments in my comment above.
Where do I find the ācustom_idā?? I see custom product and custom label - but not custom ID. None of my products are custom so all say false.
Can you help?
ah I thought you meant they werent showing in google merchant centre as well. Always keep an eye on that because they shopify chanelle will say products are approved but they wont be showing in merchant centre.
If you see a large drop off on the active product graph you know you have a problem.
OKay so you inspired me and I found the solution!
I selected all products but couldnāt find the column you were referring to. But I did see that I had my products listed under a custom category. So, I changed the categories to Standard Category types, and the products were all immediately approved!
Hi, see my last post I have found a solution that has worked for us, hope it sorts you out too
I have them listed to both āStandardā and Custom product types which (according to Shopify literature) is okay.
I tried a few little tweaks on products yesterday and then they were immediately approved. However, 30 mins later they were disapproved again.
Maybe check them again in an hour or two and see if they are still okay? Will you let us know on here.
Hi,
I just did what you did - set a standard category. It immediately āapprovedā it.
However, Iāve just checked back and itās disapproved again - how are yours?
This is a known issue, Shopify has technical issues. At the rate they fix fundamental issues, on the free app, I donāt expect anything to be resolved any time soon.
The free app is plagued with fundamental issues. If you are losing sales, I recommend you move on to a paid app, where support is much better. (In my opinion)
Thanks for the reply but sorry, which app are you referring to?
The error messages Iām getting are on both Shopify and on Google Merchant. Iām not using an app for anything?
Which was it that you thought?
Any top-rated app, just not the free one. https://apps.shopify.com/search?q=google%20shopping
Same as yours! I woke up this morning and they are unauthorised again!
Have just been on the phone to Shopify, they managed to sort one product out over the phone and are sending me a step by step guide on how to fix the rest, will send to you when I get it
Thanks so much. Shopify havenāt come back to me yet. I spoke with Google today and they are supposed to be doing manual reviews. The number of rejected products I have grew today.
Would rrally appreciate you letting me know what Shopify finds out
I actually have the same issue since the beginning of December. A year long Iāve had no issues and suddenly all products (about 60k products) do not have any GTINās set according to the merchant center. All products do have GTINās though, so there seems to be something wrong with the sync between Shopify and Merchant center.
I have also talked to shopify support and they couldnāt see anything wrong with my products. As I dont feel like going through 60k products of manually requesting a check, are there any other solutions?
Iāve seen someone suggest a paid app, but with the amount of products I have that doesnāt really feel profitable.
@Eren1999 said that Shopify sorted the issue for them yesterday and they were going to post the update of how to do it here.
Iāve woke up to find more products showing without GTIN in both Shopify and Google Merchant again.
Iām not looking into a paid app either as I think this is a syncing issue or perhaps even just a reporting glitch with the Shopify /Google Merchant integration and Iām hopeful theyāll get on top of it. Hopefully what they gave to @Eren1999 will work?
The solution they gave me, worked for 30 minutes then they switched back to unauthorised again.
It seems that whatever change you make, the system recognises the info is fine, then rejects it laterā¦
Iām at my witsā end with this and quite frankly wished I just ignored it as now I am on a mission to get it sorted!
The person that helped me hasnāt responded to me saying theyāve been kicked back out again when they do, will update you
It seems like both Shopify and Google are putting it in the ātoo hard basket?ā One product that I manually submitted appears to be okay now - its been about 24 hrs (but wonder if that will change again?). However, the number of products not syncing has increased.
I will follow up with Shopify again.
