The lightroom camera app will delete any photos it has not processed if a log in is forced by the app. Adobe customer service told me that this is working AS INTENDED. I spend hours on the phone with them. They obviously were aware of the problem and kept trying to blame it on me. I lost hundreds of pictures from a once-in-a-lifetime backpacking trip. I posted a review to warn other consumers and your "developer" told me this is not working as intended.
Which is it, adobe? WHY WOULD YOU BUILD THIS FUNCTION INTO YOUR APP? You could at least warn people not to reconnect to the internet before processing photos! I'm such a horrible person, I wanted to call my family for the first time in weeks and obviously should've finished processing photos first, jeez. Shame on me!.......
Also, you have done this twice to me, and the first time you made up a big story about how it was a bug that you had fixed.
I'm converting your post to a bug and setting status to Acknowledged.
We do apologize for your troubles and loss of images. I'd like to get more info in hopes we can provide developer with additional info to help them debug the issue.
Can you elaborate on your workflow so we can understand your sitation better? You captured many HDR (or perhaps Tech Preview: Long Exposure) images in the Lightroom iOS camera? Then you exited the in-app camera view to something else like Library
