macOS Photos.app - Names Missing on Shared Albums Recently the names from users of my shared album have disappeared from the activity feeds (See picture) - this has only happened on the desktop, both the iPhone and iPad are fine.

Just updated to High Sierra and hoped the issue would fix itself - but nope, still a problem. Any ideas? Searching for answers hasn't revealed anything.
Please try these steps and report back:


In Photos.app in your Mac go to Photos > Settings > iCloud and uncheck 'iCloud Photo Sharing'.
Wait about a minute for the changes to apply.
Quit Photos.app and restart your Mac.
Open Photos.app and turn on 'iCloud Photo Sharing'.
