Updated to Catalina, and LR Classic CC is gone. I would generally "pull down" Lightroom Classic CC from the Adobe icon. It is now gone! Instead, I get an adobe window a clean web-like layout. Yikes.
I have my images backed up on a separate harddrive. I can "see" and open LR 5 - (which opens in the old catalog) but the work I was doing in the LRC CC is "missing" as I cannot retrieve the correct version. (catalog)
