Same error here on the same firmware version.
The solution from samsung support to reset the smart hub is not working.
You must setup all apps after this proces again but the problem with spotify is the same.
Today the tv offers me an update to version T2003.
Now spotify works again.
Greetings to all happy samsung user.
Hey there you,
Yeah, you! 😁
