Today, I suddenly got a permission denied error on all calls of the Google Ads API to my test accounts.
I tried with a new OAuth refresh token. I do not get the error when using the manager's customer id but you have to get to the client id directly to manage campaigns. Also tried to create a new test client but the same permission denied error. I do have access to the client from the Google Adwords UI.
Test client id: 3211402788
Is there anything that has changed on your side, it was working two days ago?

Google Ads failure details:

"code": 7,

User doesn't have permission to access customer.
Thanks,
