My spouse uses IOS and I think she can do it however she only monitors one of the locations. I look at both. The android app is quite different than the IOS app. I like IOS much better in terms of friendliness.
I'm looking at my android app now. I have one location defined and it works fine. I just logged out so I am looking at the Server Login screen, the first page. In bright letters it has the name of the current site. Under that is a grayed "Add New Server ..." but when I touch it, it goes bright for 1 sec and then back to gray. Other than that, nothing happens.
** 5 mins later **
After playing around with it I discovered I could move the Add New Server button into focus. Then I was able to add the new server and am able to connect to it. Maybe that notion of those being buttons that I move to bring into focus is just new to me. Learn something new every day.
Thanks for the nudge to keep going.
