Please fix back to 1.20; I felt that I wasted time learning diagonal bridge and PvP in iOS

I played Minecraft bedrock in mobile, but I can't move while pressing the place button for 1 or 2 seconds without moving with 2 fingers; I can’t do diagonal bridge or jump bridge. Try doing diagonal bridge and jump bridge in iOS or android. It also affects when I attack player; I can’t aim while pressing attack button. Remember the video that has shadow is version 1.21.90***
