I'm using a Mac. Lightroom Mobile only allows me to sync around 3,000 photos / smart previews. I understand the number should be higher. I've removed all the photos from sync, deleted all data using lightroom desktop, cleared all cache and it still says that I'm using 38GB of my 56 GB of storage. Does anyone know how to fix this?
If you are referring to disc usage in LR mobile settings panel, these values are referring to the device capacity.
