Multi control not working

[Pankaj Kumar Meena]

My multi-control was working fine on my Galaxy book 3 360 laptop till yesterday(19-4-2024) but today as I started it, it is showing "This model is not supported. Close the application" . I use to connect my S8 Plus tablet and S21 ultra phone using multi control but now I can't do that. Please help me Samsung

Almost the same story for me. I have a Galaxy Book 2 360, S8 ultra tablet, and S24 ultra phone that all were working fine up until a few weeks ago. Samsung "Pro"'s were useless to help.
