Hello @DouglasM52 ,
The blue box in the social share function that mentions the Facebook image size is a reminder, not an error message. Error messages would show in a pink box. If you're having errors with a specific account, these are typically resolved by refreshing the API permissions with the social platform in question. This occurs most often with Facebook due to their system's regular API resets and permission expirations.
We're always happy to help!
