i love how one year (and four updates) later the what's new still says 'first release of youtube kids on tv'
i hesitate to see if that also means it's safe to update the main 'youtube for android tv' app now which had the same crash problems since the big redesign.
I recently had to roll back my YouTube and YouTube kids apps to updates from early 2018 on my leeco TV's due to the fact they kept freezing about a minute into any video played. I'd be leery of updating.
