ios 8.2 safari cant play youtube videos - dont have YT app
I just updated to ios 8.2 and then noticed that no youtube videos will play in safari. I press the play button and I get a perpetual spinning busy icon. Eventually the phone goes into standby. I can repeat this issue on WiFi, LTE and 3G. They play ok from Facebook or Google; I don't have the YT app. I've tried restarting the phone twice (32gb 5s) with no results. Some tabs in safari that had YT videos already open before the update now won't play. Going to youtube.com through safari and picking any video at random won't play. This issue may not be new it 8.2; I had recently sent some YT URL's to my mother's pre ios 8.2 iphone 5 and she complained that they wouldn't play. Pasting the URL's from safari into google ap will play. To add insult to injury, YT ad's play in safari followed by the perpetual busy icon of the YT video that never will.
Out of ideas.
iPhone 5s, iOS 8.2
