I was part of the few with 32bit / 64bit phones (mine being a 64bit) that had a bug which made using Mobile impossible (game crashed as it was trying to download the cache, every single bootup). They said a patch was coming in January (which I assume was this one) and I was so hyped when I saw that there was a patch, finally I could play Mobile!
But my hopes were shattered when I also encountered this issue, I bootup the app, it goes black, then immediately exists to my home screen. Absolutely nothing.
I just hope another patch to fix this is coming soon, I really really wanna play Mobile.
My game is loading (aka letting me sign in) but there are zero people or NPC*. I was able to mine and eventually clicked on the right area to find the banker at the GE. I did however click on multiple NPCs while trying to travel. The graphics are definitely not fully loading. I tried lowering frames per second and decreasing other graphics, restarting the game and my phone, etc. and people never loaded.
