I have a iPhone 5s with the most up to date IOS software. I use the reminder feature on my phone quite heavily and I've always never had any issues with setting reminders to go off on a specific day and time.
Up until about 6 weeks ago, it wasn't an issue but now it is. I checked my settings and they are fine. I've powered it off and powered it back on.
Help! Did Apple do something with their software recently that could have caused this??
