Stuck on building terrain on minecraft realms

Hello, today my friends and I were exploring The Nether (I was on mobile, them at PC). I was kicked out by the server when I explored my recent tabs, so I didn't "Save & Exit" this time. When I tried to re-join the realms while in the nether, the loading was stucked at "Building the terrain" (my friends told me I was on the server while I was at the loading screen). I tried reloging, restarting and re-installing the MCPE, nothing worked. Now we must load the save from when I wasn't bugged. It's really annoying.
