Book3 can't connect 2 devices with multi-control at the same time

[The-Yuri]

I used multi-control with my Book 3 for two days and was working fine with both devices.

Suddenly I got this message. Maybe after an update or something...

"Disconnect Tab S8+ to connect to another device. To connect 2 devices at once, both devices need One UI 5.1 or later."

How can solve this problem? My phone and my tab are both with OneUI 5.1, and they worked the first two days, but now I can only connect one at a time.

I tried to signing out from all devices and signed in again but the same problem.
