I am having an error message show up whenever I try to create or open a world. "There was a problem loading this world". I have looked for other bug reports finding 7 and all say "resolved". You scroll down below and you have many people claiming that it is obviously not resolved. Please do not do this to me. 

This makes it IMPOSSIBLE to play or create any worlds that I own. I am stuck with my brother creating worlds for me, playing servers, and my realm. Unfortunately, I cannot edit my realm because of the same problem.

Also, my friend was having a problem earlier today while trying to join my world. He said it told him that he was on a different version than me and we could not play together. I had updated my Minecraft app yesterday and he said that there was no new update. We tried refreshing the app, restarting his device, and reinstalling the app. Reinstalling the app removed all of his worlds and it was not worth it because it still did not work. I sometimes have this problem as well and have lost two of my treasured worlds. 

My device is an Amazon Fire Tablet HD 8 and my friend's device is an android phone.

Please help me,
