while running a Google maps route in the background and running a few other apps back and forth, the swipe down function stopped working. Two small icons remain frozen in place - the small Google walking figure in blue and the screenshot captured one. I've restarted the phone. Enabled, disabled, reanabled swipedown feature but it doesn't function. Installed T-Mobile software update today. Nothing seemed different. Very strange. I'm running an A11 bought last September.
