Hi @patryktarachon,
Can you let us know what error it is showing? If you can, please turn on logging under Marketing > Facebook and try to connect, and look at the log under WooCommerce > Status > Logs.
We look forward to hearing back from you!
I coped with the problem. You just need to do the configuration from the end. First create an ad, then set up a business account for Facebook and Instagram. Still, please keep that in mind in your next update.
If I understand correctly, the problem is resolved? If that is the case, that is good 🙂 Please bear in mind that the Facebook for WooCommerce plugin does not integrate Instagram, that requires a separate plugin.
If the problem is still persisting, please let us know what the error is.
