Wifi wall switch ,smart life with ST

Hi all
I’ve just set up a wifi switch ,3 gang running with smart life , this switch has shown up in the ST app and I can control it on/off if perfect, automation setup ok, however if I switch it on with the light switch the ST app does not know it is on ?
Based in UK
My ST app does a ‘network error’ when trying to setup anything on the smart life.
Cheers Darren
