trying to get an app review completed, and have been rejected multiple times. the reviewer is asking for a test user, but when trying to create a test user on our app dashboard, we are told repeatedly that "the ability to create test users is disabled temporarily". This "temporary" state is now going on three weeks. any idea on why this would be?

While trying to finalise "required action" and connect app to verified user I am getting error:
Something went wrong. We're working on getting it fixed as soon as we can.
This happens since week and apparently no one is fixing it. I also don't see an option to contact FB directly ......

Hi When i try to create a facebook app with link to a business, it show the above generic error, the app was created but no business account tie to it. Without that, i was unable to setup Whatsapp API for the app.

We have to integrate fb login into our app, but to test the integration we do not have any test user. So when we go to create the test user we are getting message that "the test user creation is temporarily disabled by fb". So just wanted to know when fb will enable back to clear test users?
Thank you

I am really struggling and unable to get any form of support from Facebook. We are being asked to connect our developer page to a verified business.
I have verified my business eventually, as for some reason my usual FB account was restricted (no idea why, no right of appeal, no way to log into that account on the developer page now and no way of asking for help).
I set up another FB user and have eventually managed to verify the business but when I try to connect my developer page to the business the next button is greyed out. I believe I have the correct permissions.
Image attached of where I am stuck.
Any ideas would be greatly appreciated.
