Hi,

Have you found a solution for this?  
I have recently got a Samsung qn90ca and when trying to change the source through the Samsung Smart app the same error happens.  
Factory reset and creating a new token didn’t help.

Hi  
No I haven’t found any solution with homey. I had to go back to my Harmony remote system to had it worked.

OK that’s too bad.  
Then I just keep using the key options to browse through the menus.  
Thank you for your reply.
