SO frustrated. Even Apple help on phone can't seem to fix this. I have about 900 contacts on my MacBook Pro and 600+ on my iPhone 8 and same on iPad. WHY? One reason is, duplicates is not working on laptop! It's not catching duplicate contacts that are THE SAME. I have all synched to iCloud. Same issues with my photos, not matching. I so wish someone to just FIX this in person! Save me! Such waste of time and energy. HOW to fix this? Why aren't they the same total number of contacts and photos?! BIG Thank you!!
