I'm trying a different game install from the one I was using and I'll let you know if it works. Yes I have been using exfat, I also can't change this miscrosd to fat32, there is no option for that when formatting. I think it's stuck as exfat because of the 256gb size of it. It's this microsd card...
Theres a tool to format fat32 but ive ran into problems using sx os and cheat features using exfat because its memory is fat32 im sure it said in a release note.
