I don't have direct contact with the developer.
Originally my understanding was devices were placed in order that they are added to the app that may have changed with one of the updates.
I can ask Authinx if they have any insight and maybe they can see what the developer states.
However I don't believe the developer and Authinx are on the greatest of speaking terms.
From what I understand the developer is refusing to do any more work on the app or hand over the protocol with out being paid substantially outlandishly more then Authinx is willing to pay.
I'm very surprised someone hasn't hacked one of these yet.
We may be stuck with the current apps and how they perform until some one reverse engineers this and figures out the protocol.
