Icon in tray (top of screen)
I am running Android 13 with Mobile protection 18.5.0020216.
When I manually end the protection by swiping the message away, and I then manually start the app, the W icon does not reappear until I reboot the device completely.
I think I saw last week that the icon re-appeared but I am not sure. I think the icon should reappear, because my device is almost never rebooted :-)
