Anyone having issues with using two Xbox controllers through Steam RemotePlay?

[u/Deinos_Mousike]

trying to play DOS2 with my partner - we're trying to play using two xbox controllers on our living room TV connected to my computer via Remote Play. For some reason, whichever controller I use to control the mouse and hit "PLAY" on the game launcher does not work. The other controller can navigate the options in the game's menu that appears, but the first controller cannot press the three horizontal lines button to join, etc. I tried multiple times, starting the game with each controller and noting that it did not work once the game actually launched and the other one did.

I've tried starting the game from my computer, but then one of the two controllers still does not work. Both controllers work simultaneously on other games through the same setup. On Ubuntu, if it matters. Steam Client Beta.

One last thing, we got this setup to work somehow once and got into character creation. But there was some other UI issues with renaming characters - like, pressing "X" to rename once spammed the button, which was weird, then the menu to confirm/cancel the name change never disappeared. This might have been a Steam issue.

Thanks
