Push notification rarely works for email on iPad2
I have an iPad2. Push stopped working maybe a week or two ago. On rare occasion one will come in. My settings have push turned on. I moved the mail to the top of the Notification area. I then shutdown and restarted. Still push email not coming through. Before that I deleted iCloud and email accounts and recreated. Still no change. I tried changing the sound, emptying the trash from other random recommendations to no avail. Very frustrating. Any new suggestions are welcome. I don't have 3G. I use wifi (64gig).
