Game crashing 2 sec lag first parry,wifi and screen loading

With August update i am facing new issue with gameplay movements in quest basically.At the start of every fight game hangs at 1st parry with 2 sec lag.while loading contents game takes longer time than last month.And also one more problem while i was playing arena i encountered an error team already in for fight this happened due to a new kind of wifi bug. I had already selected a fight and wifi bug came in when it was gone i loaded arena again and game took me to a team selecting screen after selecting team again an error said team already in for fight it took me almost 20 min to get back in arena fight.
