Hopefully this is self explainatory but I will elaborate.
(Mac OSX Catalina - LRC 11.0.1)
During import, I occasionally get the 'destination drive is full...' and the only option is to press ok. At this point, I clear space from my drive, empty the trash and hit 'ok'. The import is nonetheless cancelled and the smart preview generation begins. I then have to go back into the import module to reimport the new photos, wait for the preview thumbnails to generate on a card or phone that can have hundreds of photos or just blindly hit import. This isn't ideal as I can no longer use the 'previous import' filter to apply a mix of metadata tagsor assign different collections on subsets of photos in one swoop. It would be nice to just pause and resume when the drive space is resolved.
