Re: Switching YouTube tv channels takes two minutes.
Roku is rolling out version 9.3 of its firmware and it sounds like you just got it. You can confirm your version via Settings > System > About. Problems are starting to be reported with numerous channels under version 9.3, and we've seen lots of complaints re YouTube and YouTube TV, among others.
