I use /e/OS 4.2.a14 official on a Fairphone 4, and recently, the X app has been consistently minimizing itself after just a second or two. The app doesn’t close; it just minimizes—remaining active but invisible. Bringing it back to the foreground causes it to minimize again, making it impossible to use. I have to access it via a mobile browser instead. Is anyone else familiar with this issue?
It comes through OTA. As you are on official, you should get it too. If it does not show through Settings → System upgrade then it is probably the staggered release and you need to wait a bit. Or enable testing channel as described in that page. Or download the image and do a local upgrade - I have never done that and cannot find docs right now, but searching this forum probably helps, it is a frequently discussed topic here.
