USB file access (MTP) not longer working after upgrade

[Martin_Anderseck]

USB connection to PC: FP2 icon appears, but "this folder is empty"

When connecting the phone you’ll get a notification on your phone as well. Tap on it and you’ll see different options what the phone can do with this USB connection. Default should be charging only, so you’ll need to switch to MTP, then your files should be available again.

You might have to swipe down to see the notification.
