What causes Lightroom to re-sync everything?
Usually when I open Lightroom there are a few photos to sync. I'm using the mobile app on my iphone, so it'll sync the latest images from my phone.
In the last couple of days, when I open Lightroom, it seems to want to re-sync all images in my cloud which is about 15,000 photos. Unfortunately this seems to take up much of its resources because any other kind of browsing grinds to a halt at this point and often it just seems to crash getting the Mac OS "Application Not Responding" message when you right-click the App icon in the dock.
Is there some sort of sync cache that has been corrupted somewhere?
