Elytra Multiplayer Fix

The elytra in multiplayer is goofy. It looks like I’m standing on another players screen. And the velocity of the elytra doesn’t match Java. The wind charges also don’t boost me up high enough from the velocity of the elytra. Please mojang fix this glitch/bug. I would love to have this glitch fixed because it looks really weird and upsetting. It demotivates me from elytra mace.
