iPhone SE - Playing YouTube Audio with Browser Closed
So I've been doing this without issue for about a year. Once I minimize the browser, the audio would temporarily stop. I'd swipe up to get that shortcut screen. Swipe to the left for the audio control, and hit the play button. Never had an issue. Now, suddenly when I hit the play button the title of the YouTube video disappears from the audio control and it doesn't play anything. I then have to go back and start the YouTube video from the browser. I tried it from my wifes phone, who also has the SE, just to masked sure it wasn't YouTube somehow disabling this functionality. Hers worked just fine. Does anyone know if there is a setting I may have hit to disable this? I use this quite a lot, as I use YouTube often as workout music and have other windows open like workout timers. Any help is appreciated.
iPhone SE, iOS 10.3.1
