Won't stream 4k. Not sure why but this app has decided it no longer can handle streaming the 4k movies in my collection. Also there are movies that used to be 4k that are no longer showing up in the 4k filter. As for the bug, every single movie will just spin away and never load. Left it sitting on my desk and nothing ever happened after 10 minutes of waiting. I miss the days when Google was a company you could trust.
