I setup shared photo library with my wife and initially it worked, but since then not a single photo from her or me have sync’d. Manually adding them has not worked either after waiting a week to sync. This issue is occurring on all our devices, iPhones, iPads and Macs. All devices are up to date and each device was checked to make sure shared library is enabled and automatically sharing. Spoke with Apple, who suggested the usual reboot and reset everything routine which did nothing to resolve it. They escalated my case, have not heard back for two weeks. Anybody have any suggestions. Really like to try and resolve this before the holidays.
