Mac Photos Albums syncing incorrect images randomly.
I have a large Photos Library on my Mac (16,000+). Many images are sorted into Albums.
When I sync all Photos to my iPhone, all of the images are transferred and all Albums from my Mac are visible.
Some of the images in the synced Albums are incorrect. The majority are okay, but a few photos are randomly changed to images from different albums.
This has only happened recently. I have tried removing all photos and resyncing, and even a full reset of the phone. Some photos, seemingly at random, change each time.
I am using a MacBook Pro 16-inch & iPhone 12 Pro Max, both with latest OS updates.
