Hello. I have two Kindle Fire 7s (one is running FireOS 5.6.8.0 and one is running FireOS 7.3.1.7) and in the past few weeks Minecraft is no longer playable. After going through the world-creation process and finally clicking "Create" after a few seconds it always says "There was a problem loading this world."

Tried these things already:

• restarted Kindle Fire
• removed Minecraft and redownloaded from Amazon App Store
• restarted Kindle Fire again
• deleted cache and memory for Minecraft
• restarted Kindle Fire again

Problem persists. All other non-Minecraft games seem to be functioning normally. 

Thanks for any help you can give.
