Ugh we also have an open support ticket for this, I'm going to copy/paste my response from there here:
Hey, you say the login for both apps are a challenge but only list issues with the UX for the unlock app, what issues did you have with the control app?
a)
Agreed.
Hrm, not heard of this issue before, possibly caused by debouncing. (Actually see what Lokki said, I forgot this option existed....)
We fixed that a few days ago I think, please update and test.
Weird, possibly due to wifi/3g not connecting quick enough?
Yea this is a limitation we're facing.
b)
Probably a combination of your phone and your ring.
Yea it probably would, the read radius is much larger anyway so reads are easier.
I will close the support ticket and we can work on this here :)
