Glad starting from 0 works in your case.
For others it won’t work. Facebook locks the business commerce account and won’t let you delete it in order to create another one.
I’ll say this again… starting from scratch is not a solution. The problem hasn’t been fixed.
Either Shopify of Facebook needs to fix it. You shouldn’t have to pay anyone to “fix” this and no “expert for hire” can fix it either. Anyone offering to fix this is a scammer.
Of course Shopify promptly marked this as FIXED so it looks like they did something but this is issue is NOT FIXED.
