I already responded to the other thread about this in more detail. But, my god, the game has become unplayable in coop on my end. It seems to just be PS5 players experiencing this?
I appreciate all the tips and ideas shared in this thread though. I may try the idea of taking slow turns with actions. It makes sense that my husband and I doing actions at the same time might be causing the cursor glitch with jumping and combat (obviously the combat being the real game breaker for us, since it renders characters unusable). I'll try it and if it is consistent enough, I'll include it in a report ticket when I get to submitting one properly. My husband is not a creature of patience so this probably wont be enough for us to keep playing, sadly.

Hoping praying they find a way to mend this sooner than later!
