Libadwaita apps not reponding to tablet input

I have both a wacom intuos pro M and an XP-pen tablets working but pen pressure is not responded to in any way (so I can’t click anything) in any libadwaita app (all others I’ve tried work just fine).

Is there a fix and/or non-libadwaita package manager I could use (one with a setting to de-prioritize libadwaita results so I can more easily find apps that I don’t need to grab a mouse / use the wacom’s touch-pad functions for?).

Not that this is deal-breaking but it is annoying as I generally put my mouse away when I have my tablet connected and find the palm-rejection of the touch-pad inadequate for just leaving it on so I’d prefer not to need it.
