Q:

Beta app is shown in the browser but not in Google Play?

I've published a beta of my app in Google Play.
I can see it with my smartphone and I can install it with a different account from the developer account (just to be sure).
Now I try the same with an 'old' tablet (Android 7.0, Google Play 6.1.12) and if I click on the link to the app: 
https://play.google.com/store/apps/details?id=com.infinitymundi.anima
it tells me 'element not found':

if I try to cut and paste the link in the browser it shows the app:

It even shows the Install button, but if I click it gives me 'element not found' again.
My app is built with Unity and it's compatible with Android 6.0+ (I deployed the same app in this tablet with Unity and it worked).
Any suggestion?
Thanks!

A:

I've found out that you need to download an unofficial google play services update from here https://www.apkmirror.com/apk/google-inc/google-play-services/ and it worked.
Maybe this is strictly related to my tablet model (a Xiaomi).
It will be useful for others, I think.
