This happens when either:
a) You reject the permissions prompt shown when the app opens.
b) Another VPN application is set to "always on" mode.
You can investigate (b) by fishing around in the system VPN settings
and seeing what's there, possibly removing authorization for those.
Afterwards, close the application, reopen it, and it should prompt you
to accept permissions.
We'll happily accept a patch automating this kind of thing, if the
Android frameworks allow it.
