Xbox One keeps me signing out since March 2020 update

Hi,

Since the latest, March 2020 update (which brought the simplified dashboard as well), my console keeps me signing out. The internet connection is okay, and there was no problem with it before. It is really annoying, acutally I cannot use the console as by the
time I am signed out, every game kicks me out immediately with losing all the progress I have made.

First of all, is there somebody having the same issue? Do somebody know any solution?

Am I the only one who think it is weird that: 1.) a game just kicks me out without any alerts, losing every progress, and 2.) there is no even at least an option to sign in again immediately and continue?

Also, since this update my Download Queue window closes all the time after a short time and the console goes back to the Dashboard home screen. Is this intended? Is this useful? I always want to check download queue, and listening to music or do soemthing else
until a download is finished, but now I can't as I would have to open the screen again and again and again and again.

:)
