I have Sangoma phone on Mac, release 3.9.2 (or any other really).
Scenario:
Install the package.
Launch the app.
Put in the info.
It goes to trying, forever, never times out, fails, or logs in. I assume because of a typo or something.
Quit the app.
Remove the app by deleting it from “Applications”.
Install the package again.
Launch the package.
It immediately goes to trying, without letting anyone enter the credentials again.
So where did this information get stored? Since it seems to not be in the package directory, as it is retained after a deletion.
