@adwords-API, does Google Ads API Compliance have a similar forum somewhere that you can point us to?
We are still down, have filed many tickets with them with sporadic and unhelpful responses, and nobody at any level we've talked with at Google is any help. If they could simply rollback their changes even it would help immensely but we can't get a hold of anyone on that team to help.
Note to the forum: DO NOT use Google's "Token Transfer" option to move your access token from one MCC to another. Ever. We suspect that it's bot-run and there's no human in the loop, or their mistake on our accounts would never have happened. And once they take an action, there's no way to get them back, to revert their change, or anything. This is the definition of monopolistic behavior.
DO NOT USE Google's Token Transfer option within Google Ads API Compliance.
