Just a thought. Some report that they are successful in disconnecting the IG account from FB, and converting it to a personal profile. Then, leaving it for a few days before converting it back to a business account and connecting it to a new business manager account. I don't know, but better than abandoning the account completely if that's the only option left.
Hi @PaalCoffee, apologies for the late reply! I managed to get it to work by disconnecting Instagram and Facebook, deleting the catalogue and then tried again a few days later. All good now, fingers crossed!
Thank you again for replying to my post. Much appreciated.
