Cannot play youtube on lock screen
Before the latest IOS I could play a youtube video on my iphone and it would stop when I lock/turn off the screen. When I hit the play button on my headphones it would continue with the screen off so I could listen and not waste the battery. Now when you hit play on the headphones it starts the MP3 player. Even if you pause the video by hitting the home button and open the swipe menu the player shows the video text, but when you hit play it changes it to MP3 again. It's like the new IOS automatically reverts to the MP3 feature even when you have another player/application open. Does anybody know a way around it?
Thanks
iPhone 5s, iOS 10.3.1
