I edited about 20 photos on my phone yesterday -- cropped, altered saturation and contrast etc. This morning, on my phone, those edits have all reverted to the original photos.
I use iCloud library. The photos had not completed uploading to iCloud library before I edited them. My phone uses ios 11.3
Can these edits be recovered now that iCloud sync up is complete and those edits are reverted to the original photos?
EDIT: given that there is no solution, and that others report the same problem (and that it happened again), I have filed a bug report at Apple:
