Hi all season's greetings

I have a Deco M9 plus with 3 units a Huawei router, what I notice a few days now is I'm not seeing my smart home devices in the app they're all connected to the network and working good I can control them with their own app its just I can't control them in the deco app because I'm not seeing them, not sure whats going on with them see attached the deco app,  does anyone have this problem. Thanks Roper
