Recently discovered this:
Uninstalling Unity Game form Android device (not yet tested on iOS) and then re-installing the same game will make the game grab the deleted PlayerPrefs to show up again in the fresh installation of the game!
Even this:
—> went to App info in android and i manually cleared the app cache and data
—> then uninstall the game
—> install the game again
—> boom, PlayerPrefs values are back!
I was not noticing this prior to 2019.4.5
Can anyone help?
