Reopening a discussion on Zipcar App (USA based)

Hey all,

I am trying to get the Zipcar app to work. However struggling with it, as it is unclear which part of MicroG is not hitting. Wondering if anyone has had any success with e/os 3.0?

I am theorizing that it is related to the bluetooth part, as when I have bluetooth off it immediately kicks back that it cannot log in, but with bluetooth on it takes a while before it posts something is wrong.

I already saw this from last year Some android apps can't authenticate
