1. Edit photos in the iOS native photos app
2. Import photos into Lightroom Mobile
Observed behavior: edits made in iOS are lost - the original photo is imported instead.
Expected behavior: honor the edits made in iOS
The workaround I'm using now is to Export the photo to Google Drive, re-download it from there, and then import into Lightroom Mobile. Not a scalable process.
1. Edit photos in iOS native photos app
2. Import photos into Lightroom Mobile (either from Lightroom Mobile or from the iOS camera app itself) with option to preserve edits made in iOS (i.e. export the file with the non-destructive iOS edits permanently baked in)
I don't think LR Mobile can read the edits done in the native iOS app.
It is best to pick one image editing workflow (Program) and stick to it.
