A follow-up here to my posted steps in how to eventually get photos synced via the newest version of iTunes:
As I had previously stated, performing all of these tedious steps DID successfully get me back to where I was before the iOS 11.3/iTunes 12.7.4 tragic combo was foisted upon us all. FY, I am syncing with Windows 10 to both an iPhone X and an iPad Pro. After performing my recommended procedure, I eventually resynced approx 1200 of my photos in (25 different sub folders), I did notice that the overall TIME it took to complete a routine sync was somewhat lengthened. Before, “Step 5 of 6 Reading photos....” had taken 10secs or so, before moving on to the next “Analyzing.....” step. but the “Reading...” step now takes me between 1-2 MINUTES before it moves on to completion. That said, ALL my photos WERE synced successfully, and were in their correct folders. And one thing I didn’t mention (which I saw that some others had also encountered, and has occurred with previous versions of iTunes) was that after closing the iTunes software, you weren’t able to START it again, without logging off/back in, or restarting Windows.
For many of you who tediously reverted BACK to iTunes 12.7.3 to attempt to rectify the situation, I’m sorry to hear of your pain. This entire problem is a direct result of an horrific conflict between iTunes 12.7.4 and iOS 11.3...PERIOD! I just now saw on the Web that Apple is besieged with bug error complaints about iOS 11.3 and will likely be pushing out a NEW update to iOS 11.3.1 as early as this week to attempt to address all these complaints of failures! Apple support? NO! They told me they were “looking into the problem”, but as TOO often, they didn’t have so much as ONE clue about how to HELP us (news flash there, eh?!) All of YOU, out there in the Apple Community, are MUCH better advisors in helping to make our devices work as they SHOULD. Considering the big $$ we all pay for them to begin with...a crying shame for sure.
So hang in there everyone. Slim hope here that a new iOS 11.3.1 might help even a little bit. But keep your discovered “fixes” coming, Apple should pay us ALL for proving them to the Community!!
