I recently merged a library of about 110,000 photos into my iCloud Photos library, using an iMac running Sierra. The process went slowly, but well and I can see the photos on other Macs and on my iPhone 6S running iOS 10. However, my iPad Air 2 started often crashing when I loaded the Photos app. At first it was intermittent, but now it is constant. I've tried disabling iCloud Photo Library, but it still crashes. I've alternated between downloading all photos and optimizing storage and that does no good. I've tried force quitting the Photos app, restarting the iPad, etc. Today, I even downloaded the latest beta of iOS 11 to see if that might do the trick -- the Photos app still crashes.
Is there a way to completely reset the Photos app without wiping my iPad as a whole? Is there another way to try to fix this?
