Front door requires bypass if open

I have just installed this system and now just found this flaw. Really annoying. It’s just not like any previous alarm systems I have used.
As we go out in dribs and drabs it’s always the last person arms the alarm and invariably the door is open at that point.

It’s a MAJOR security flaw in that if the warning is ignored, then the whole alarm is not set.

What is really really annoying, is that no one from Ring actually provides an explanation as to why it’s a good idea for existing behaviour, and why the new behaviour cannot be accommodated. It’s just the same old stock reply from Ring.

Come on Ring…explain yourselves.
