When inviting a visitor, if they are invited to more than one site, it disconnects them from the previous one. This is not ideal as we may have a visitor going to more than one site. It would be better if we could invite them to duplicate sites, then those requirements remain there like they do for workers. Doesn't make any sense in a real world application. It does make sense to not allow them to sign in to two different sites at once, but the requirements for each site they have connected to should remain visible, not be hidden because of an auto-disconnection.
