Samsung TV logs out automatically

[Domlaw]

Hi, I have a Samsung TV (the frame 65”). 

The Spotify app keeps logging me out and I need to either log in with password or use connect to get going again. This is somewhat frustrating.

Any suggestions? Thanks.

I got the exact same problem (55") but most of the time it doesn't let me log back in. Just get an error "unable to log in to Spotify at this time". 
After like 15 times (totally random, can be 3 can be 2 days) it suddenly lets me log in.

Exactly the same problem here with a Samsung 65mu9000. After 2 days or so it logs off. That  you need to go to apps, reinstall and only than you can log on again. Otherwise it rejects the login even though username / pw is correct. Very annoying!!!!!
