POE2 BUG with joystick-multiplay

I am a player who enjoys playing in split-screen mode with my brother. During our split-screen gameplay, we have encountered several issues. I would like to report them to you as follows:

When playing together in split-screen mode, we are unable to reroll rewards in the Ritual Altar(refreshing does not work).
When playing together in split-screen mode, we are unable to designate P1 as the party leader (this causes strange issues, such as being unable to activate Atlas maps).
In certain acts, such as Act 3 and Act 6, there are many strange bugs during split-screen gameplay (e.g., after returning to town, the characters become unresponsive, and NPCs cannot be interacted with).
