PUBG Mobile BUGS

Im from ANDROID and switch to iPhone because of my friends that they are telling e that iOS is well optimized when it comes competitive games like PUBGM. But when i tried to play like TDM and Quick match i have encountered bugs like in TDM when starting the game i see no enemies nor teammates but i have heard foot steps and gunshots and this is not what i am expecting. Kinda disappointed on that moment.
