Alexa Q990B Soundbar doesn’t support that

Hello,

I have a Samsung Q990B soundbar with built-in Alexa enabled. I used to be able to say, change sound bar input to HDMI one, HDMI two, Bluetooth, etc. for the past month, the sound bar replies, the sound bar doesn’t support that.

I have tried, resetting the sound bar, deleting the SmartThings app, deleting the sound bar from the Amazon appand enabling them. I used the phrases with routines that I had previously set up, and now they do not work.

I have read through other posts , That some integrations were recently removed. Is this related? Is there any other way I can reenable these functions? I have tried to go to the devices web address to get a status reply, but it reports an undefined error. I can control certain functions of the device through the SmartThings advanced web UI. I do not see functions to change the source input. I would appreciate any help or guidance. Thank you.
