Unable to add scenes - Unauthorized Client error

Hi,

I am trying to add a scene to one of my panels. When I click on Add Scenes button, it takes me to SmartThings authorization page and then I get an error "Unauthorized Client" even after a successful login. Please note that I have tried this several times on PC (Chrome browser) and phone (Google Pixel 3XL, Android 11 on Chrome browser), it gives me the same error.

I am aware about the workaround which involves creating a virtual switch and an automation. Wanted to know that if this feature (adding a scene directly as a tile) is still in beta?

Thanks,
SK
