I can export 1-5 photos at a time from Lightroom back to my camera role, but I cant seem to do multiple at a time. if I select 5-10 (or more) images it fails without an error. Doesn't matter if I select "small - 2048px" or "maximum available" same result. If export 1 photo it gives you the brief popup "one photo successfully saved to lightroom album." Same problem on my iPad pro and my iPhone. Is this something that will get fixed?
Slight typo in my title, should be "cannot export multiple photos to camera role."
iOS only. I have an iPhone X and an iPad pro 10.5. Problem is when multiple photos are selected (approx over 5). Doesn't matter what the format is I am exporting to, it just doesn't do it. It goes through the motions of "downloading smart preview" and then "rendering 1/5" though "rendering 5/5" but it never says "5 photos successfully saved to lightroom album." If I check where it exports to the photos are not there.
I think it's an amount of available ram problem as it works with fewer images. Somewhere after 5 images it starts to have problems.
I also tried this myself (iPhone X, iOS 12.3.1, LR 4.3.1), and I didn’t see this issue. I exported 6 images (at small size) and got “6 photos successfully saved...” and they are in fact in my Lightroom album.
I wonder if it matters whether the images are on your device or it’s pulling from the cloud? This shouldn’t matter if you chose small size, but maybe try it with some freshly taken photos just to be sure it’s not a cloud sync issue?
