As soon as I updated to 1.19 I started having audio lag and issues with chunks of the world not loading when walking/flying over them. This is a survival world that I play by myself. When I load in I give it a second to render, I start to walk and I hear nothing for about 3 seconds and all the delayed audio rushes in and overrides the current audio and this repeats throughout the gameplay. When I fly or walk over land, even previously loaded land, there will be parts that are invisible, and while flying I won’t be able to continue. I just stop in mid air and start to descend with nothing loaded below me. I deleted Minecraft, which I knew would delete all of my worlds but I just wanted to be able to play even if it was on a new world. After re-downloading Minecraft I started up a new world and I’m still having the same issues as listed above. I play on the iPad Pro 11” iOS 15.5.
