Guys this is terrible. You pushed out an iOS update and required that everyone be on the latest V16 in order for them to work. Let me translate that for you: YOU BROKE EVERYONE'S MOBILE APP. And there is no way to go back once an iOS app is updated. Seriously, who thought this was a good idea??? I was going to use 3CX for a few other clients and now I'm having serious doubts as to your judgement as a software vendor.
And something else, when signing up for a login on this thing, why do you make people enter their phone number in an international format? Nothing I entered worked.. couldn't do 011, +1, +011, 1. Nothing. Turns out you have to enter it exactly as +1 949.. (with a space between the +1 and 949, even though the example below the field shows +19491234567). Come on guys..really?
