I completed the Data Use Checkup for my application and when I clicked submit I got an error
An error occurred while submitting the Data Use Checkup. Please try again later.
What should I do?

I initiated the business verification process but did not complete it. It is in the "Pending submission" status now. It was a couple of days ago.
I am trying to resume or restart the process, but it fails every time after I select the verification method—no matter what method I use—call, email, SMS, or domain. The flow simply returns to the original screen. Previously, I was able to download, for example, the HTML files for domain verification.
Is there any way I can reset the process, restart it or resume it? Anyone knows a solution, or at least an approach to this problem?
It is either a bug, or I am missing something.

I faced an error "Meta for Developers is not available in this location." How can I fix that?
