Am I right that the only Calendar that will be visible in both the lead organiser and family member's Calendar/s at the same time is the "Family" Calendar i.e. the one that bridges both 'domains'? Is it not at all possible for a family member to see other Calendars in the lead person's account if they are logged in to a different iCloud account? Can the family member be given access to more than one shared Calendar? It is quite frustrating if this is not possible as my wife can only see a very small proportion of calendar events on her iPad and iPhone that are normally entered on our iMac that we both use under a different iCloud account.
