Input issues on iphone 14 pro max

Ujara

The input issues seems to be worse when I’m doing battlegrounds or aq. I swipe forward and I dash backwards. Like 5 times in a row. I try to do a heavy and I dash backwards. Same thing when I try to do a parry stun. I blamed my poor gameplay on my galaxy s7, but now on my iPhone the game still runs like ****. Any clue when you can make this game run properly?
