I cannot set the heating zone manual  mode from the Android Phone App.   I can enter the desired temperature, the duration and when I press Save I get a message that says "Cannot Enable Manual Mode".   I cannot disable it either if it is set from the web app.   Currently on HC2 with V4.140 but didn't work under 4.130 either.  On the phone I'm using a standard user not the administrative user to connect.   Same on the Android tablet app
