We've noticed statuses of our ads being updated to WITH_ISSUES, and an error message we don't quite understand.
Questions: - What is causing this? - What "Action" is being blocked here? - How should we resolve this?
A workaround we've tried is to set the ad to PAUSED / ACTIVE. It works for a while, but the ad soon reverts back to WITH_ISSUES after.

The endpoint that we are using to fetch page's follower count is NOT working as intended.You can see that it returns incorrect/negative numbers.
