After releasing our app for a few internal users via the Play Store Internal test track, we moved to closed Alpha testing. However, for some of our Alpha testers, the new update of the app is not visible at all. All of these users have opted-in to be part of this test track too but, when they access the app listing on Play Store app, they see an older release and not a build that was released several hours ago.
Some of these users even see the update that was pushed a week ago! Even for one of the developers who has access to the Play Console who got the notification of the update gone live when tried to go to the app listing sees an older version only. What's surprising is that these same users can see the latest version on the web version of Play Store.
I've tried multiple solutions based on this SO question like Play Store Force Stop + cache clear + data clear + network change, etc. Nothing worked for me.
