Received a mail from Skyverge saying:
Several other users are experiencing the same issue so our team has been working with Facebook to address this. The Facebook team has notified us that they have found the issue and are rolling out fixes to affected accounts.
Would you please give connecting another try to see if the patch has been applied to your account? Once we have reconnected your account, I’d be happy to help connect you to the Facebook support team to help with any Instagram account issues – our plugin doesn’t integrate directly with Instagram so they’re best suited to help in that case.
Tried again and same error. This problem is costing us money every day.
Plus connecting me to Facebook support team will be a nightmare, as it’s the worst support team ever, no knowledge or willing to help.
I’m already checking how to install the pixel with Google tag manager.
