Topic: Youtube 360 vids not displaying correctly

I've always been able to watch youtube 360 videos on my PSVR headset without problem. But recently, the image displayed is enormous and there seems to be a horizontal divide through the middle of the screen. It's like the bottom half of the image has been rotated clockwise 90 degrees. It's not displaying properly at all

Has anyone else had problems recently/can suggest what the issue might be?

Thanks!
