99+ % match rate on July 21 and before that. 0 % match rate on July 22 til now.
Google approved my app around July 11, and I have had over a 99 percent match rate every day from July 11 until July 21. When I woke up on July 22, the match rate was 0, and it has been 0 ever since.
I have checked the following:
The policy center says: "No problems." I have also never encountered any issues in the policy center before. I have an app-ads.txt file that says: "Found and verified" and has a green checkmark. My app is on the app store, and Google states that my ad serving is activated.
Things I haven't done:
I haven't submitted the US tax form in the payment section. When I go to the verification tab, it only says, "Your account may need to be verified." I haven't made any changes in the code. I released an update on July 17, and the app had a 100 percent match rate with that new version (that version had the marketing URL in which the app-ads.txt is stored) until July 22.
What I think is wrong: I believe that on July 22, Google found and verified the app-ads.txt, and I suspect that after the app-ads.txt file was found and verified, my ads stopped working.
But I don't know for sure, and I am desperate for help. My app relies on ads (otherwise, users have to pay for it, and the fact that it is powered by ads is one of the main selling points). Right now, this ad problem is killing my app.
The error message I am constantly getting is this:
