I am a photographer using LightroomCC. I export my images into Creative Cloud Files and then into individual folders. When I open the folders the images appear but the 2 buttons at the bottom "choose" and "cancel" have disappeared and/or hidden. I cannot figure out how to retrieve them and they are not part of the toolbar at the top.
I wasn't sure exactly how you were opening the files to where these "choose" and "cancel" buttons should be appearing. Could you post a screen shot of when they do appear and what you're seeing after the export where they're not appearing?
