I'm still having the same issue. I have gone to the step where I have set up a new FB ad account, new commerce account, new IG account (!!) and gone through all the various steps and recommendations. Currently I'm working on presence on the new IG account to have it approved for IG Shopping. Will post when I get any further.
My impression is that this isn't necessarily on Facebook. Or, to be specific, it's probably on the way Facebook's sales channel app connects Shopify to Facebook. A while back I noticed that there is a catalogue connection set up with Shopify as the owner. This catalogue was automatically set up when I connected Shopify to Facebook and Instagram (in the old sales channel apps). This catalogue is owned by Shopify, and my Business Manager is a partner with access to it. So I am not allowed to make major changes and delete it.
In other words, the catalogue resides in Shopify's Business Manager, and it's connected to my Facebook page and my Instagram account.
This is where I think the problem might come from, since the error message says "This Instagram business account is already linked to a Commerce account on Shopify". Shopify won't reply to questions regarding this, they will just tell mee to go to Facebook with it. Facebook will tell me to check that my IG is properly set up and appeal through IG, IG will give me some automated reply that doesn't help at all.
Another thing that I've been thinking about: one of the error messages I have been getting from IG is that my account isn't approved for IG Shopping due to products not being available for direct purchase on the website associated with the account. If the IG account, through my FB page, is connected to Shopify's Business Manager, and Shopify's Business Manager has done something with the settings there (don't know if it's even possible, just a suspicion), that "locks" the account to Shopify's business manager.
Hi @jonliow - no, still struggling.
I'm pretty sure the problem here is that I initially used Shopify to connect to Facebook Business Manager, but in that process the catalog was created in SHOPIFY's business manager, and I only have access to it. Shopify is listed as owner in my Business Manager. It's still there, and I'm unable to get any help from Shopify - they just claim that they do not do this, pretending it's a non-existing issue.
I know this thread is a few weeks old, but I am in the same unfortunate position in that I am getting the same message. Facebook support are pointing the finger either at Shopify or Instagram and Shopify is pointing the finger at either Facebook or Instagram. I am just wondering if you got a resolution to your issue? Thank you in advance for any help you can offer.
I'm sorry, we gave up and started fresh with a new IG-account, new Ad-account i FB, new commerce account, new setup in Shopify with the new Facebook integration. That turned out all good. I still believe it's a problem with the old FB-integration from Shopify creating a catalogue owned by Shopify, prohibiting me from making changes. This catalogue then made a mess when I removed the old integration, and that we have not been able to fix it. I have no clue why it would make IG reject our shopping request, their response was that the registered website had no products available for direct purchase. I was able to get some help, through a FB Marketing Expert (the ones that contact you by email when you have a certain ad spend over time). He was told by some "internal Instagram group" that the reason was probably that I had listed my website without the leading www, and that IG was then not able to access it as it would default to http, and not https. It all seems like b*ll$4!t to me, as ANY proper web app should be fully able to redirect with/without www and regardless of http/https.
Anyways, in short: we gave up after 6 months, and started fresh. Works 100% now.
Thank you so much for getting back so quickly. As much as I would like to start afresh, I have a following of just under 3K on Instagram and that was hard work. Maybe I'll start with disconnecting Shopify from Facebook and see if that possibly is the answer. It is super annoying that I have taken out quite a bit of advertising with both Facebook and Instagram and I am paying Shopify every month and none of them are helpful tbh.
Thank you again for getting back to me, much appreciated.
I don't want to crush your hopes, but we also had thousands of followers and spent tens of thousands in advertising in the timespan in question. Still, nobody at FB/IG would acknowledge the problem, and nobody at Shopify were able to help. I believe that Shopify has a Facebook Business Manager account (or several) with LOADS of catalogues for our stores, that are now useless and unavailable for us after the upgrade to the new Facebook integration. They all probably know it, but they don't want to take responsibility for it.
My 2 cents...
And btw, we tried EVERYTHING, and new accounts was our only way out. I cross my fingers and hope for the best for you, but I'm not a believer on this matter. Sorry.
That is just crushing you had to delete your IG account, etc. I have now gone and deleted everything Facebook on my Shopify. And still a data source is hanging on in my Facebook Business Manager that I cannot delete. I will find a different way of getting products from Shopify up on Facebook.
Thank you so much for taking the time to get back to me, very much appreciated. Wishing you success with the new setup!
