So first, flying using elytra is now impossible since the update sometime after 1.16 because the world doesn't load as fast anymore while gliding. Here is a video https://youtu.be/UKdhOxqKuw8. Also there are other bugs like me not being able to join some worlds using mobile data and it is stuck at "connecting to external server". or me not being able to join any world after leaving the app and coming back. And it gets stuck with whatever the first loading screen message displays. This needs fixing. Those are the main issues
