Major downside if you using AirPlay
Update 2/24/16 AirPlay problem again. The previous version fixed AirPlay. This version AirPlay kept spinning. Cant read comment on video. Have to use the native YouTube app again. Load slower than the native YouTube app. Cant AirPlay to my Apple TV or may be it take it time too long and I have no patient. Switch to the native YouTube app AirPlay play immediately to my Tv. Hopefully, the developer will fix this issue in future update. For the meantime, I paid for this app but have to use the YouTube app in order to AirPlay. still cant play AirPlay. Very disappointed
