Photos not transferring from iPhone to iPad
iPhone Photos taken yesterday are not showing up on my iPad yet…normally they appear almost immediately.
iPad 2, iOS 9
Are you using iCloud Photos, and not the now-dead My Photo Stream (which stopped accepting new uploads in late June)?
Is iCloud Photos enabled on both devices under the same Apple ID?
Has the iPhone been connected to the Internet, so that it has a chance to upload photos to iCloud?
Has the iPad been connected to the Internet, so that it has had a chance to download them from iCloud?
