Thanks for your detailed reply. I tried the Android app again today and it seems that there are a bunch of options to do the things I want that were not accessible the first time I tried. I can’t explain it. Maybe the app needs to be restarted to give access to the zone details and other things. In any case I’m on my way to figuring it all out.
I’m a programmer (Windows and Linux) so I too am used to bad software, but when it is really bad and there is no ready help available I get annoyed. Having things like help files containing nothing but “Coming soon.” leaves a bad taste in my mouth.
