The Play Store says the Wear OS by Google companion app is getting a beta, but it’s unclear what it’s for.

Our colleagues from 9to5Google have spotted the Play Store indicating that the Wear OS companion app will be receiving a beta, but it’s not yet clear what new features it will bring.
New apps open beta on Google Play Store
Yesterday, Google released a new update for its Wear OS app, which hadn’t received one since last March. This version 2.57 is the last stable version of the application, but the changes are not obvious.
However, you can try to join the Wear OS by Google beta program via this direct link. 9to5Google note that other Google applications are in the same situation: YouTube Music, YouTube for Android TV, Google Clock, Google News and Google Play Books. He notes that those who tried to join the beta programs are still pending and no new versions have been rolled out.
There is no reason for this situation.
At this time, we therefore do not know if there has simply not been a deployment of these betas yet or if it comes from a bug in the Play Store related to the test phases. A priori, existing beta version applications continue to function normally. Moreover, we do not know exactly why several Google applications would enter beta at the same time.
Wear OS continues to improve
What is certain is that the operating system dedicated to Google’s connected watches (developed in collaboration with Samsung) continues to develop. Recently we learned that Google Assistant will arrive this summer on the Galaxy Watch 4. Also, a new set of APIs developed by Google and Samsung will improve connected health thanks in particular to connected watches. Google believes in Wear OS and connected watches: during Google I/O, it unveiled its Pixel Watch.
