My iPod Touch 5 and iPhone 5 at the same time sounded the reminder tone/ Alert default tone. I have reminders during the week all set at 6:00pm and this sometimes happens in iOS 6. I am on iOS 7 beta 6. No banner came up but I have banners on in settings. I was using my iPhone 5 on tapatalk and my iPod touch 5 screen was off and the reminder tone sounded on both devices at the same time. Any fix? please reply! Ask if you need any more info.
