@andrewilley so this is insane: I tapped on the three-bar menu icon at the bottom right corner, the menu opened, but upon tapping the settings button, nothing happened.
I raised my eyes to my PC screen to type a reply, and as soon as I looked down to my phone again... PA was back to normal!
Anyway, thanks for the tip, sir! I'll make sure to export all that data, just in case!
