My team is still being affected. See this thread. There are many others suffering from this problem too.
Our experience has been public for several weeks and we started our first sponsor almost a fortnight ago now. For no reason we can discern, it feels like our experience has been blacklisted, and my own Ads Manager account just appears to be locked out of making another sponsor campaign.
This is very disheartening.
We would all deeply appreciate if you would look into this issue for us.
