Apple also had to open up to Android with Apple Music in order to be able to appeal to more users. Since the launch, the group has repeatedly been in the process of distributing improvements.
9to5google found out that the current beta version comes with a new sleep timer. You can set this by jumping into the three-point menu in the current playback and selecting the option there.
The timer can be set for 15, 30, and 45 minutes, for one hour, or to stop playback after the current track or at the end of the current playlist. Furthermore, the widget is also improved with this version.
If you want to become a tester, you can sign up for the beta through the Play Store.
