Assuming there are no issues with your account’s standing and the page in question, the warning should clear up within a few days. If you are still having an issue you can contact support.
Sadly we can’t share details about how the warning works because scammers literally joined our discord making believe to the legitimate developers seeking information about how it works trying to reverse engineer the system to continue distributing scams.
For others reading, only a small set of users are impacted by this warning message.
Thanks!
