Minecraft can automatically update to a beta version, while there is no participation in the beta programme, as seen in the image(Screenshot_210134-1.jpg). The previously installed version was release version 1.21.31.04. the newly installered version is beta/preview 1.21.50.20

In the other screenshot({...}_Minecraft.jpg), minecraft is indeed switched to the minecraft beta version. This is visible, because there is debug text at the top of the screen, and the spalsh text says: "bèta".

Steps to reproduce:

1. Search for app updates in google play store.
2. Update minecraft.
3. At the "What's new" header, version 1.21.50 is displayes, and the app version changes to 1.21.50.20.
