How to install the alpha version of the Google Play app for testers?

Question

Google

Good afternoon!
Created an alpha version of the Android app. I posted it on Google Play as an alpha version, published it.
In the settings of the alpha version, I registered the Google+ community for testers.
I sent an invitation to join the Google+ community on my phone (Google account, which is different from the developer account). Joined the community and received a link (url) to join the application testing.
The link opens on the phone, and it is proposed to become a tester and download the application from the Play Store.
But, in the course of the Play Store, it is reported that "File not found".
More than two days have passed since the publication of the application, which is more interesting, the Play Store link opens on the "big computer" under the developer's account, but on the phone it doesn't :(
Help me please.
Sincerely, Alexander.

Very strange, I re-published the alpha version, and after an hour everything worked...
