@PsubondYes recent Dice updates recently broke portal for Xbox Series X in the following ways:
Portal at times hides servers for no apparent reason.
When switching to "Followed" server list inside Portal, the "Followed" listing shows up for half a second then goes back to "ALL" servers listing.
Switching between game mode categories does not work anymore, all servers are shown in all categories.
Portal now auto-faults to hiding full servers, and you have to switch it back in search every time you refresh as it does not remember settings.
Portal still puts you in the wrong selected server at times.
If you back out of a portal server, it sometimes simply locks the Xbox Series X up completely with a black screen and you have to hard boot the Series X.
In Summary, "Portal" and Xbox Series X don't get along very well...
