I tried to visit a group (e.g. Ecosystem Guild of the Salish Sea) on hylo with occasional posts by its creator, and when coming back to it after the Hylo redesign I thought I came across a broken site or something because I felt like I couldn't find any of the Ecosystem Guild posts. I tried clicking on 'Stream' which didn't help. I believe this felt even more exacerbated on mobile web where it wasn't obvious that child posts were enabled.
I came back a day or two later on desktop and still experienced the issue. Eventually I realized one has to click and disable the button "Show posts from child groups you are a member of" to see the posts I was looking for.
Perhaps there's another way to approach this design? Is it the responsibility of the group owner/admin to appropriately setup 'child groups' properly so such confusion doesn't happen? Or is there a different placement for the "Show posts from child groups you are a member of" button? Or a default that makes "Show posts from child groups you are a member of" disabled by default?
Does the wording/framing around 'child' or 'parent' groups need to be thought of differently?
