When I set mine up on Friday, by Sunday it had said I had 40,000 photos and it was up to date, but I have 53,000 photos and it stopped updating. I tried turning off icloud photo library off and on again, but that made things worse, as it wouldn't download photos at all.
I plugged my phone into my computer and delete the photo sqlite database with ifunbox and it started downloading again, overnight I was back to the same 40,000 photos and now my albums are empty.
Been almost a week and still don't have my photo library full synced. I have it on plugged in and I can scroll though the photos and get them to come in. another annoying thing is the screen keeps flashing when pictures are loaded. I picture will load, show the thumbnail, flash back to gray show the thumbnail over and over again.
It's making me want to throw my phone across the room very frustrating.
If it says updating be sure to connect it to the charger for it to copy over your photos.
I chose to setup from a back from my iPhone 7 Plus. Unfortunately everything but my pictures transferred over. I use iCloud Photo Library I’m wondering if anyone else had the same issue ?
Well, I finally got mine transferred. I did a hard restore using my mac and iTunes and that still didn't work so I went to the Apple store to talk with someone at the genius bar. He messed with it for nearly 1.5hrs and concluded my best bet was restoring it again and setting it up as a new iPhone then connecting it to iCloud iPhoto and seeing it would download. I asked what the difference between that and disconnecting iCloud's iPhoto from my phone which was already up and running vs doing that. Then I did the turning off the iPhoto in iCloud and turning it back on then it miraculously started downloading. My advice is to make sure it is connected to wifi and plugged into a charger.
