My AC Samsung AR12HSSFAWKNEU never see in app Smart Air Conditioner (CAC)

I had a Samsung Galaxy S7 edge and there was installed app Smart Air Conditioner (without CAC termination). Now I have Note 20 Ultra and single available app is Smart Air Conditioner (CAC)… but device not found in network.

I set from remote control AP to blinking, but device cannot be found… The same in Smart Things app…
