For example: Suppose I was finished playing V9 and for some reason I have to reset my phone.... So I copy the saved files from the Data folder to a pendrive or a different folder.
Once I reset my phone, I install V9 or the latest V10, open it once and the go back to the Data folder to paste the old files, then Android 11 doesn't allow you to paste it back. It seems Android 11 is designed in such a way that you cannot make changes to the files in data folder other copying from it to a different folder.....
