I signed out of my account on the Lightroom app about an hour ago. When I went to sign back in, all of my photos were removed from my account. I do not sync with a desktop library, it's just my mobile account. I did not do any updates on my phone or the Lightroom app. Where did all of my photos go and how can I get them back?
Go to lightroon.adobe.com and sign in with your Adobe ID. If you have synced files with Creative Cloud, they will show there, and you should be able to re-synch them with your phone.
