I opened lightroom app on my phone but now when I tried to upload photos from my computer, I can't because the lightroom is connected to mobile files..
pls help! how can I sync my desktop lightroom with the pictures on my computer??
You can sync both ways, that is, from Lightroom desktop to Lightroom Mobile and vice versa however, you can sync only with one catalog on Lightroom desktop.
I did not get the exact issue. Could you please explain your workflow?
