Hello,
I've encountered the same issue. Here are my details:
Minecraft PE for iOS on iPad
3 player Realm
I'm the Realm admin
First occurred in MCPE version 1.0.1, still happening in 1.0.2
Issue started when I was fighting multiple Blazes in the Nether. I got hit and the game crashed. Haven't been able able to get back in. The only exception is if I switch the Realm to Creative, I can get in. But as soon as I switch back to Survival it crashes.
When I log in it says loading, syncing pack with server, done, then the screen goes white and takes me to my iPad home screen.
The two other Realm players, both on the same home network and wifi, can still access the Realm.
Twice when I've attempted to get in I got a "global resources" crash error.
Stuff I tried to remedy the situation:
Restarting MCPE in multiple ways (logging out of Xbox Live, not signing out of Xbox Live, hard reboot of my iPad before launching app, etc.)
Installing 1.0.2 update
Deleting Minecraft app from my iPad and reinstalling it and my worlds
Hope this helps.
Sandra
Thank you, Mojang developers! The issue has been resolved in my Realm.
