nevermind this was fixed after restarting my nintendo switch
@silentwhisperer This bug may be the same one or a variation of it as I tested the ways to replicate that glitch and it seems it may be the same one, there are just different ways to cause it. This video I have attached, "suffocation glitch.mp4" was taken after using my elytra.
Yeah I have this exact same problem, it is so annoying I can't figure it out. I am playing on windows 10 on version 1.16.201
I can confirm that this is still a problem in 1.16.220, how to recreate:
fly into a wall (in survival mode) so that your elytra disengages,
then, walk into a block floating 1 block off of the ground,
and you will find that your head glitches through the top block,
you will find this also works with any blocks off of the ground including 2 block high ceilings that you jump into. Developers, please fix this, it has been in the game for the last three updates.
