YouTube NOT working!!!!

I’ve read other posts/comments about this same issue. YouTube doesn’t work directly from the tv itself, or when I try casting it. YouTube is very much a need in our house, as I use it for bed time routine for my toddler. She falls asleep to fruit dance by Hey bear, and then once asleep, she sleeps to twinkle twinkle little star 10hr loop with dark screen and galaxy background. Ughhhhh is this a glitch with ROKU right now? YES, I have uninstalled and reinstalled 4x, that is NOT the issue. Please help!!!
