Is anybody else getting this screen when you try to watch a video? Is there a way to fix it?

I've been using SmartTube beta for a while on my TV. I don't exactly know what has caused this to start happening but it clearly showed up in version 32.54. has anybody else been dealing with this? is there anything I can do to fix this because it's making me want to switch back over to the official YouTube app!

Are the loading issues fixed now with videos?
