If you restore your data stored in the cloud the issue comes back. So you're going to have to kiss your worlds goodbye if you want to play Minecraft "normally." I'm just waiting for an update, which we will hopefully recieve soon. But I guess you could play without your old worlds until this issue gets fixed.
Yup, still having the same issues after 1.11.0. I'm also getting disconnected from servers within 2-3 minutes.
Yes, it seems that the only current solution would be to delete all of the save data. Before 1.12.0 I had constant lag/freezes ingame, but 1.12.0 fixed those issues. Now I have this... I decided to keep my previous stuff backed up to the cloud. I was able to access my worlds by using airplane mode when I had my previous data installed.
