I regularly update my shared calendar on iOS 11. It syncs with my iPhone and iPad both running iOS 11 but my friends and families calendars on iPhones and iPads (which are all non-iOS 11) are not being updated. Any ideas of a work around?
iOS 11 not updating shared calendars
a quick update. Having checked my Macbbok it appears that it’s not updating Calendar on that or when I look at iCloud.com it’s Unchanged there so suspect it’s some sort of iOS 11/iCloud sync problem but strange it updates my devices ok
I’m was getting the same today however the behaviour seems erratic.
My various calendars all (except 1) shared with others.. and when adding items in to the Calendar (shared with others) on the iPad Pro 10.5” running iOS 11 beta 3, they never appeared on my iPhone 7 running iOS 10.3.3.. despite it being done a number of hours prior.
I then created entries in to the shared calendar on the iPhone and they never appeared on the iPad.
I then created an entry in an unshared calendar on the iPhone and it immediately appeared on the iPad Pro.. then an entry in a shared calendar on the iPhone which appeared immediately on the iPad Pro.. then an entry in a shared calendar on the iPad Pro and it immediately appeared on the iPhone!
So, not sure what was going on there.
