In support cases users also report the following:

If you try to add the add-in back, you get an error "Something went wrong".
Some users cannot search for it under All apps > Add Apps.

STATUS: FIXED

This issue was investigated as service incident EX1183224.

Final Status: We've identified that a recent backend change caused add in management requests to fail, resulting in inconsistent cached data and add ins appearing unavailable for some users. We've rolled back the change and refreshed the affected cached data to restore normal add in availability and confirmed with some impacted users that this has successfully remediated the issue.
