Hi, since I have the new iPhone 16 Pro the Lightroom mobile app won't load any new pictures I take with the phone. It only says: photo can not be loaded. Error Code A100000. dng_error_unknown - ReadNegative SmallOriginal. 

All the pictures I took with the old phone or new ones sent to me via WhatsApp etc still load just fine. 
Does anyone know how to fix this? Thanks so much!

    I am having the exact same issue with these errors and all of my photos from my iPhone 16 despite my app also being up to date. Were you able to resolve this?

    Agreed. I'm having the same issue with photos taken with my iPhone 16 pro max. I have the latest versions of LR mobile and iOS. Anyone figure out a fix yet?

    Hi @Charlie.D, thanks for the reply! 

    Yes, this concerns all the photos captured by the iPhone 16 Pro. 

    I am updated both to the newest iOS and LR App. 

     

    I tried offloading and reinstalling the App like you suggested, but it didn't fix the problem. Do you have any other suggestions?

      Hi again @charlotte_2679 

      Are these images actually on your local camera roll, or are they in iCloud?  It shouldn't matter, LR should still be able to fetch iCloud photos on demand. But if that doesn't happen smoothly due to a poor connection, then I wonder if that could cause this.

       

      I have the same device, and cannot reproduce this, so I'm hoping to get more clues about how your app got into this state.

       

      I will send you a separate message asking for a diagnostic log.

      Hello @charlotte_2679 

      Are the image you are trying to import captured by the iPhone 16 Pro, or captured by another camera?  The error code you mention indicates the Lightroom's Camera Raw library is having trouble with the images, and this doesn't usually happen if the image type / camera is known.

       

      Are you updated to the latest LR iOS app version 10.1 (or newer)?

       

      If you are a user of the free app, I would not recommend deleting the app to try re-install.  Deleting the free LR app will also delete images that exist inside the LR app.  

      Instead, please try offloading the Lightroom app, and then restoring it.  This will preserve the app cache, while re-installing the app.  Here is how do offload/restore Lightroom iOS:

      1. Open Settings > General > iPhone Storage
        2. Scroll down, select Lightroom, and tap Offload App
        3. Tap Offload App again to confirm if necessary

       

      Then to restore/re-install Lightroom:

      1. Go to Settings > General > iPhone Storage

      2. Find Lightroom, and then select Reinstall app

       

      Please let us know if this helps, or not
