How to participate in the internal testing of the Google Play game?

Question

Google Play

I want to test the game on my phone. Made internal testing (it is available) appointed testers (indicated the necessary mails).
1. via the link to the mail - the link does not open well (the site where you need to accept the agreement does not load well - I can’t accept it in all browsers on my phone
) download it from Google Play" - I open it from Google Play, it says: "File not found"
I would like to see a link somewhere in Google Play notifications

Answer 1

The same nonsense.
At first I thought it was due to the fact that the first time a publication for internal testing can be checked up to 48 hours, but after 72 hours nothing has changed.
They have a warning there that due to COVID-19, all checks and work may be delayed, but it is not clear how much longer.
But I do not rule out that he did something wrong. I also added my mail for testers, I sent the link. Everything also ends with "File not found".
Maybe someone came across and still was able to solve? Or do you just have to wait a long time due to the pandemic?

Apparently, it is still related to the pandemic and all the delays in release checks, which are warned about in the Google Console.
I waited from the 26th to the 31st and finally posted the release for the beta test.
