Comment 5 for bug 1989120

@Ian, had you previously done the connection manually by any chance? I found that connections persist through `snap remove/install/refresh` so I had to `snap remove --purge juju` to test this properly.

I should probably test this out on a fresh system but I can assure you that switching from 2.9 to 3.0 didn't do the auto connect. This transition was done initially using `snap refresh juju --channel 3.0/stable` in my case.
