I had the same issue just popup on my new Hisense Roku TV. I'm watching live television and it keeps taking me back to the Netflix login screen. What's weird is the sound is still from the live TV, and the profile icons are showing what is on live TV.
Has nothing to do with the remote. It's a software glitch.
I fixed it by opening Netflix, scrolling to 'Exit Netflix' to close out of it, and went back to watching live TV. It's been 60 minutes and it hasn't popped back up yet.
