I like to backup the flashcard database a lot just in case, but lately when when I press backup database instead of directly allowing me to save to google drive, it just shows the internal memory. I can't find the option to change it back. Can you help me?
Is 'use legacy file chooser' turned on in Settings / Miscellaneous? Turn it off if so.
If it's already off, what brand / model of phone are you using? Some OEMs (most notably Xiaomi) screw up Android's built-in file manager screen so badly that we're forced to not even offer the option + always use our own file chooser instead of the system one.
