OK guys so this is what's been going on with my two nexus 7's. YouTube was working fine and all of a sudden it just won't play any other video. Its like its stuck on playing one video and every time I click on any other video it just plays that one video. Let me further clarify. This issue is with the HD videos only. That video that is stuck is also in HD. And let's say  for example, if I click on say 'payphone by maroon5' then it would start playing that video that its stuck on in stead of playing the actual song but when I click on HD button to disable HD then it would start playing the actual song video but in SD.

I called Google and told them the problem and the rep on the phone sent me a replacement. Well guess what? After a few days the replacement has stared to do the same thing. Only this time its stuck on a different video. I am pretty sure others are having the same issue. Now, I have reset both devices multiple times, cleared the cache and force stopped the YouTube, restarted the device, installed YouTube update/uninstalled, disabled/enabled YouTube app, signed in/out of YouTube app, etc. Noting works. Hard set don't work either no matter how you try it. By the way Google rep knew about hard rest problem and said that is a big issue with nexus 7 and according to him Google does not send out a replacement if u are having hard rest issues.

Please, help me out in fixing this YouTube app bug.
Thanks.
