I've successfully imported my Lightroom Classic catalog into Lightroom CC. Overall things seem to be working fine, but the counts are off between my iOS and Mac devices. Both Macs report 30,872 photos while both iOS devices say 30,865—so off by seven. Any idea what's going on or what to do about it?
How many images are there in the web version? (https://lightroom.adobe.com). You can try seeing if signing out of the CC account on your iOS devices, deleting the app, reloading the app form the app store and signing back in helps. I've seen cases like this myself where some images just refuse to sync and all devices still say everything is synced.
The web version is consistent with the desktop version—it reports a bit differently but if I add the photo and video totals from the web side I get the desktop total.
I tried deleting and reinstalling the iOS app, but no luck. Interestingly, I've imported new photos since my last post and while the totals are thus different from before, the discrepancy (7) is still the same.
