When trying to import photos from my SD card Lightroom CC is stuck at the phase "Checking free space on disk". The local storage is on my LAN NAS (FreeNAS) with more than enough free space. Also local hard drive is full of free space. Windows can see the correct free space on both NAS and local drive.
Import of the same files from the same SD card to Lightroom 6.0 is working without any problems.
Update: after several minutes the import continued but was very slow.
Working with LR CC is becoming unacceptable, if those issues are not fixed in a month I'm giving up on the subscription. It's not worth it. I lose less time with moving my files via USB disk and sharing on Google Photos rather than relying on Adobe Cloud...
