I customized the meetings module form, and somehow the bottom of the page with “Scheduling” where you can invite multiple people through clicking “Add Invitees” is completely missing.
I checked against other form configurations on another CRM installation, and looked at the previous revisions of the form - there’s no item to add through the form editor that would cause this to show (or not show, if removed) that I can find.
Any ideas why this has vanished?
