Family sharing invitation not working.
My family signed up for Apple Music family subscription, and I'm trying to join, but the invite link in iMessage does not seem to be working, after I tap to view invitation, and tap "Join Family", nothing happens.
I tried joining using the organiser's device using the "Invite in real life" method and I did all the steps but its says "This action could not be completed at this time."
I have tried signing out of iCloud and signing back in but it doesn't seem to work either.
Both devices are on iOS 11, and each of the devices have the same account for both iTunes and App Store and iCloud.
Please help.
iPhone 5s, iOS 11.1, null
