I have about 9,000 photos in about 30 folders that I sync to from phone to Windows 10 PC. I sort the photo's from my camera roll, into the appropriate folders on my PC and then use iTunes to sync them back to the photo's app on my iPhone X in their respective folders. iPhone is running 11.3 and I was able to sync fine until I updated to iTunes 12.7.4.76 and now I just get to step 5 of 6 "syncing" and it just sits there. I can still back up the phone -I just can't sync.
I contacted Apple Support and a case was created, and ended up going to a senior tech who had me delete the photo cache on my PC. When I connected my phone at that point, iTunes deleted all the photos and folders from my iPhone but then could not re-load them on. So it actually made a bad situation worse. I have now lost all the photos from my phone and cannot re add them again until an update to iTunes is released.
Its not the end of the world, but it is very frustrating to not be able to have the pics on my phone at the time of year where I take the most and also share them with people.
I suppose I could spend the money and upgrade cloud storage to a capacity that would support the photo syncing, but I would much rather do that on my computer.
Is there another work around for this issue anyone has discovered or are we waiting for a software update? Has anyone heard that Apple is acknowledging this issue? The senior tech I was working with hadn't heard of it.
