Ever since upgrading to iOS 10, I've had a persistent problem with photos. Issue 1: When I plug my iPhone into my Macbook Air (running 10.10.5 Yosemite), the Photos app says there is nothing to import. But I've taken hundreds of photos/videos on Camera Roll. Is there a way to get the Photos app to recognize what's on my device again? The Mac app starts automatically when I plug my phone in, so the computer recognizes it as a device - it just doesn't think there are any photos to import when there are hundreds. I'm running 10.10.5 Yosemite and I don't want to upgrade to macOS Sierra. I'd prefer not to have to do a clean install of 10.2.1 on my phone, but I will if I have to. Issue 2: Less important, but still annoying - I have a few photo folders synced to the phone, and for one of them, it will only show photos dated as far back as March 2015. Any earlier in date, and they are not displayed/stored on the phone for some reason. There are no differences in files types or formats, and were all viewable on the phone with iOS 8/9. This issue began with iOS 10. No idea why. Thoughts?
