Apparently if just took a long time to show up?
I checked with client.meshtastic.org and confirmed the radio was set up right, and the channel showed up there. Then I got distracted and when I came back to the Android app, my channel was there.
I guess maybe the webapp client may have sent something for the Android app to get a clue?
Whatever. I'm not going to risk breaking it now that it finally has shown up.
