My question is more about the mobile app. It gives me no option as to where to save. Just goes into the ether. I am trying to make it available in lightroom classic but no dice. Export works on the desktop cloud app though (a lot of detective work to find it in "lightroom saved photos" in onedrive). So confused. And why would the mobile phone app have more editing options than the desktop app? (Namely selective edits).
I've branched this post to a separate thread, since your reply was originally to a very old thread on a different topic.
Can you provide more details (maybe a screen shot) showing the process you use for saving the files? When I do this, I have options for saving to camera roll or Files (this is with iOS. If you're using Android, the process may be different).
