When i use the elytra and a rocket on the realm on my iPhone it freezes up.  Then when i force close the app and load it often will hang and never load after the loading resources screen.  On my Xbox One with the same login the game seems to play fine.

This is has happened two nights in a row, im not sure if it is a realm server bug or software.

it seems that the speed i move at breaks the realm as i noticed it freeze another time when i was quickly sorting items into chests.
