I have a set of DNG images that were imported into Lightroom desktop and then edited. When I try to export these (17 images) as jpg's the export progress bar hangs indefinitely without exporting anything. The images sync succefully and I can export them on mobile on my phone and ipad.
I have tried reinstalling lightroom and logging out and back into my CC account with to no avail.
I have had the same problem with jpg's that were imported into Lightroom.
I have also tried turning harware acceleration on and off with no change.
