I had a bug start yesterday morning on both my iPhone 6 and iPad mini. Both were running 8.1.2. My email was not being pushed to either device until I open the email app and it checked for mail. All the emails would then load. I updated my iPhone to 8.2 and the issue was still present on it. It's still happening today on both devices. Has anyone else seen this issue? Any ideas on how to fix it? I've restarted both devices which didn't help. Thanks.
