I've exported my save from the web version and have it downloaded on my phone but I'm unable to import it into the game. I get told "You don't have permission to access content of this folder"

What can I do? The game hasn't asked for permissions and I tried giving it storage permissions but had no luck

I could reproduce it too. I've just pushed 1.5.3 exclusive to the android version, it should fix the issue (and prefill the dialog with kemopop.save)
