Managing permissions and login credentials to access Microsoft Advertising accounts
It appears to be a coding flaw in their A.I. as to why so many people's new accounts are getting banned or terminated.
These generic responses from Microsoft are a slap in the face; they know full-well that there is not an actual human being going through these applications to start advertising on their platform.
What they can do is, is get a team of people in their tech department or hire a coder to evaluate the bad coding that seems to be populating with these issues so people can actually use their platform, correctly.
That is if they value their consumers, which Microsoft clearly does not.
I say just try using Google Ads instead.
