Sharing Calendar On Iphone Not Working. The shared private calendars you join appear in calendar on icloud.com and on any device that’s signed in with the same apple id and has calendars turned on in icloud settings. Try these fixes and get your iphone calendar search working again.
To share, open calendar, tap calendars, and then tap the i in a circle next to an icloud calendar. You should also make sure the calendars are on and set to back up to icloud.
