Can First Impressions volunteers check in via Church Center app and have it update the Services plan?

Answer

Enable Services integration and either match location names exactly to Services teams, or (Threefold's recommended approach) use one generic 'I'm Here to Serve' location - volunteers check in manually at a manned station the first time, then Check-Ins remembers and auto-checks them in as Volunteer (including via Church Center app) on subsequent check-ins to that event; manual manned-station check-in still works alongside it.
