P: Mobile: Offline export fails despite having “stored locally”

OK, I assumed you were working with original files in the cloud. So testing again using smart previews synced from Classic, I agree that there appears to be a bug with the "Largest Available Dimensions" setting, as that should simply export at the 2560px long edge of the Smart Preview....but it doesn't, as it reports the file is not synced. However if I use the Custom option, and increase the long edge above 2560 px (I was using 4000 px in my tests), then exporting with the network offline does in fact work, i.e. the export is up-sized accordingly. "Small" also works when I'm offline, so I'm not sure why that doesn't work for you (suggest you verify that you definiely have the smart preview stored locally).

Thanks for your reply 🙂

Those ARE smart previews as coming from Classic, not cloudy. I've set it the setting to "largest available" in order not to have to worry about dimension and JPEG quality at 100%. So this shouldn't be an issue.

I've tried with 2048px and it also fails, it's definitely a bug! 😉

It will depend on other settings....check the Lightroom settings>Cloud Storage & Sync tab to make sure that "Only Download Smart Previews" is NOT enabled. If it IS enabled, then "Store Locally" will only download Smart Previews for the images in that album.

But even if you only have Smart Previews, the export should still work without a network connection provided that, in the export settings for the export type you are using, the "Dimension" field is set to less than 2560px....so either use "Small (2048 px)" or "Custom" and choose 2560px or lower. If it's set to "Largest Available Dimensions" and you only have a Smart Preview stored locally, then yes the export will fail when the network is unavailable (assuming the cropped diemnsions of the image exceed 2560px on the long edge).

If you tap on the cloud icon next to the Share icon, the app will tell you what you have stored locally, i.e. either Original or Smart Preview.
