Currently trying to figure out how to do the same, on either connect app or browser
In the browser, just go directly to the instances, URL, tap communities, and then tap local.
In connect, there is "about instance" option in the ellipsis menu of a community list. On the next screen there should be a "view communities" option. However, selecting a community on there doesn't always go to the right one.
I go to the home page of the instance using my browser, click the “trending” drop-down at the top, then click “explore communities”.
It’s weird that it’s buried under “trending”, but at least it’s there.
Note - I’m doing this in iOS. Not sure if it’s the same in all systems.
A community for the mobile app Connect for Lemmy.
