Was able to get an answer on this issue. Mojang is aware of the problem will be fixed on next update 1.11 set to be released on May 7th 2019
I’m having the same issue in iOS. I have a iPad Pro with 32gb storage available and 3gb of system ram available. PLEASE FIX. Many times I’m traveling with no WiFi and wont to download my realm to my iPad to play it
Can confirm. Same issue on IOS 12. Also can not change texture packs
