After experimenting with LR CC + 1Tb I decided to downgrade to 20Gb bundle because of issues with sync speed and high resource usage. I now need to delete all the photos which were uploaded to CC but can't find a way to do it. There's an option inside LR Classic preferences to delete the CC library but I found that only the Cancel button is active - the Delete button is greyed out.
Does anyone know how to do this. ?
As long as you're happy you have all of your photos in Classic, go to https://lightroom.adobe.com > click the LR icon top left > Account Settings > Delete Lightroom Catalog.
