It has been over a year and I really regret that I went to my Samsung TV setting and upgrade the software. I am warning you all if you have a TV that it is built since 2015 - do not upgrade the software, I think.
Mine went to bad luck and support said there is no way to downgrade the OS version. After upgrading my TV the connection between Smarthings phone to TV has been lost. They are not communicating any longer. I have tried to fabrik install my TV, my support did so many things and he said that it need to send to reperation-store. Support said that he thinks there is issue with my network. My network has been fine and has called reperator too and it is all great. The router is very close to TV which is funny. BUT when you turn on the TV and you go Spotify, Disney+ or other apps it works, which means this TV has no problem with Internet. I beilive that there is something bug with OS or Smartthing app.
Like I said, it has been over one year and I compalined to Samsung to fix the bug but they just ignored.
Has anyone got the same problem like I have?
I really miss to call bixby to turn on or off TV.
The routine-app is useless now. Can't do anything.
