I tried many days to solve this problem but in vien.
It displayed the following message "There was a problem with this request. We're working on getting it fixed as soon as we can.".
I emailed facebook and shopify support but so far no reply.
Hope someone can give me advice.
Same problem. Support has not helped. Tried every browser on every device I have. Gave it time to fix itself. Still not fixed. Any ideas?
Is this what you're talking about? Annoys the hell out of me too!
