Care to share? Looking for something to poke around on to get started with it

I’ve been using the 8bitdo ultimate but I’ve had a few issues with it over time. For starters the rb button sticks, which I’ve been able to work around using the back paddles, but it’s still not ideal. Recently though I’ve had a few games misinterpret the buttons, playing through animal well the a and b buttons performed the same action so I had to get my old 360 wired controller out to play through it. Looking in the software (only available on phone and windows, no Linux support as far as I’m aware) showed no mismatch of setup or anything so no idea what’s happening there. Playing death stranding recently also had issues, it was as if it was trying to switch inputs from the controller to m+kb constantly.
