iCloud: Photos and Videos not the same on iPhone iPad and Mac
My MacBook Pro 15' (2017), iPad Pro 11' (2018) and iPhone 13 Pro (2021) have different photo and video counts in the photo app. All devices are conneted to the same Apple ID. iCloud photo sync is turned on on all devices with the setting: Download and Keep Originals.
MBP: photos 18'812 videos 727
iPad: photos 19'117 videos 731
iPhone: photos 19'091 videos 729
What's wrong here and how can I manage to have all photos and videos (same count) on all my devices?
Adding a new photo or removing a photo from any device will automatically add/remove the photo from all other devices.
