Since the update this morning I can no longer edit any worlds. I tested even single player zero add-on worlds and the issue persists. I simply get the loading screen (screenshot attached). I let it sit for up to 20 minutes. I have to restart the app to try again. Can open and play worlds just fine. Can get into "settings" once the world is open, but many things cannot be changed there. 

I even created a brand new world with the new Pale Forest Biome, still can't edit. Just loading screen forever!

I also restarted my phone entirely as that fixes many issues and made sure the very latest update was installed! Could not find any other reports on this issue.

Thank you!
