Thank you for your patience as we worked with our partners at Meta to resolve this app connection/authentication issue.

The Facebook Conversions app has now been updated by their development team. There is no manual action needed, and you should no longer see any authentication or connection problems due to the original error.

The Facebook Conversions (for business admins) version of the app may have some lingering errors, and we are working further with Meta on this as we speak.

We will keep you updated here as we have more on that as well.
