Does anyone have an issue where the Switch Pro controller drops connection to the deck?

I just got the 512 OLED (I’m new to the steam deck in general). And the steam deck official dock.

I connected to my TV with HDMI and was playing Spider-Man remastered. The controller kept dropping connection and I wonder if I have a weird setting I need to change.

Is my deck becoming inactive and thinking I’m not playing because there is no action on the deck buttons itself?

I also have a PowerA switch controller I haven’t tested yet.

I’m looking into buying the 8bit duo ultimate to have another controller that can go between my Switch and Steam Deck - but I don’t want to get it if I keep having Switch controller related issues.

Any advice is helpful- thanks! I’ve been in love with this thing
