Hmmm. The only issue I know of is that the game doesn't work on android 11. But I never saw anything about not being able to install... Perhaps you don't have enough free space?
I have 16.38 GB remaining, but no worries, i'll just wait for a next update and see if i can install it in a next one, thanks for the response btw
