Samsung Phones

Can anyone help
ipad pcs and iphones all control shac normally
Have tried 2 samsung phones and tried to access 2 different shacs with the same results
You can access the shac and it reads the state of lights etc but cannot switch them on/off
Maybe its something stupid!!!!!!!!!
Thanks

 

We think we have sorted it out
It appears whatever browser samsung use must of had an update and it appears not to work well with shac
If you use chrome or another browser on the samsung phone it works ok!!
