I run Lightroom CC on a Mac Desktop and a Macbook as well as an iPad. I also use Lightroom Classic on the Macs for legacy photos, testing and backup, I still don't trust cloud alone. When sorting out the stopping of syncing between classic and CC I noticed that there was a difference in the number of photos between the Mac Desktop and Macbook in Lightroom CC. On the desktop, iPad and via Lightroom.adobe.com there are 9526 photos whereas on the Macbook there are only 7447 yet the Macbook thinks it has finished sync.
Without going through photos inividually to find whats missing as Albums all seem intact what can I do to kick sync back into life.
