All my previews have disappeared after upgrading to Lightroom Classic CC
I have an iMac and a Macbook Pro.
I've just upgraded from Lightroom CC (2015) to Lightoom Classic CC. Seemed to work fine. My catalog is on an external hard drive. I've then plugged this drive onto my Macbook Pro because I need to work on my laptop.
For some reason, I'm not given the option to download the new version of Lightroom Classic CC on that laptop (WHY??). And when the previous version of Lightroom that was already installed on my laptop, the catalog loads, but none of the previews are visible. Is there a way to revert to the old catalog previews until this matter is resolved?
