I appear to have uploaded 4gb of photos that i can see at the bottom as recently uploaded, but they do not appear anywhere my "your work tab." these appear to be raw images i may have uploaded into Lightroom once upon a time, but I usually only use LR Classic and don't upload to the cloud as a rule, so i'm fairly new to the interface. Can someone advise on how to delete photos?
You could log-in using a web browser and delete directly from the cloud. That will also delete copies from any sync’d devices e.g. if you have Lightroom installed on phone or tablet. Files in Lightroom Classic are not affected.
