Back button?
I have the iPhone 7s and I don’t know if this is unique to the phone, but I am unable to go back to the previous video. Sometimes I watch a video and I’ll click a thumbnail from the suggested list below. Then I’ll want to go back to the original video, but there’s no way to do that. If I swipe down, then I’m taken to my original search or the home page.
