"Pinned Sites" in the iOS app and the "Your Communities" list on the main site should sync.
The list currently only syncs from the app to the main site, not the other way round. So any changes I make on the site only affect the list on the site, which means I have different sites pinned on the app and the site. If I make any changes on the app though, it is updated on the site.
This all started when I installed the beta, which reverted my pinned sites to an old previous state. Not sure if that is a bug or just a result of switching from the production release to beta—but I'm not too worried about that.
