frantsyI'm having the same problem with the notification panel when VPN is running.
I am having a different issue with notification panel after firmware updated to 31.1010.0410.61.
If I have VPN enabled (I'm using Netguard), when the notificaiton panel is fully opened, I cannot simply scroll up to close it, as the screen will just go scrolling up endlessly. Only way to exit this is tapping the back button. Terrible mess.
It appears that the expected message of "Device connected to xxx" is not showing properly.
