I've tried clearing cache I've use both Edge and Chrome I've used different devices

Trying to complete "Data Use Checkup" but it is telling me I must verify the business, yet it tells me business is "Ineligible for verification" ...

Impossible to create a new App.
When I try to create a game app, I get this generic error: Something went wrong. We're working on fixing it as soon as we can.

Dear Meta Support Team,
I am writing to urgently address a critical issue with the Data Use Checkup for my app, which integrates Facebook login. Despite numerous attempts and reaching out through your community forums, there has been no assistance or response from your team. My application is now restricted, preventing user logins and significantly disrupting my business.
The process has been consistently buggy, displaying an error message "Something went wrong. We're working on getting it fixed as soon as we can" every time I attempt to initiate the checkup. This is unacceptable, especially given the tight deadline imposed, which has now passed, further compounding the issue.
Immediate attention and resolution are imperative. The lack of support and the malfunctioning system are not only frustrating but also damaging to my business. I require direct intervention to resolve these checkup issues and restore functionality as soon as possible.
Please treat this matter with the urgency it demands.
Regards,

I need to complete the Data Use Checkup for my app, however it requires me to link it to my business portfolio.
I have a verified Business Portfolio already, however when I try to link the App to it, I get an error message: "Something went wrong. We're working on getting it fixed as soon as we can."
This error is blocking me from completing the Data Use Checkup, how can I get it resolved?
