Play Store - Internal app sharing does not work

I am trying to upload my app using internal app sharing last 2 days, but no matter what I do, I cant make it work. This is what I did:

1. In Console I clicked on app -> release -> internal app sharing
2. I uploaded apk
3. I added myself into email list both UPLOADERS AND TESTERS (1st tab) and also EMAIL LISTS -> Downloaders (2nd tab)
4. I even enabled "Anyone you shared the link with can download"

Here is how it looks in the console.

APK was sucessfully uploaded, and then I copied the link and saved it to Google Keep.

Then I try to open the link on my phone, I click on link, it opens webpage displaying this and when I click on "OPEN IN PLAY STORE", it just takes me to Play Store, but there is only official version available (not the internal version I uploaded).

Am I doing anything wrong? I try almost 2 days to make a simply thing like this work, and it is very frustrating...

Nothing we can do right now - Internal app sharing seems to be totally broken at the moment. Great work Google
