My Shared albums in the photos app are broken. I can’t view shared items on any device. I can’t post new shared albums or accept invitation to new shared albums. All of the pictures in my shared albums are blank. I can still see the comments but can’t post new or create new. I have ensured that all settings are turned on for iCloud photo sharing. I have also tried signing out and back in. Also turned off shared albums and back on. Please help.
