ios Photo never finish upload after switching app
I have to run the photo in the foreground, connect the iphone to power and let it run for the whole night. The message is finally gone in the morning.

However now the message has become "Uploading 38,160 items". It is attempting to re-upload everything from my iphone. My older photo are not accessible now (a exclamation icon is shown on the lower right corner on all my older photo)



There must be a more serious problem with icloud.
