iOS 11 reminder completely broken, not working Yet another major major bug with the simplest app such as reminder. I can't set the reminder for certain time. I can set it, but as soon as I go out, and in again to the Reminder app, it gets resetted and doesn't have the date set to be triggered. Completely useless app. Does anyone know how to set a reminder on an iPhone with iOS 11?
For me, I had to delete the app and re-install it from the App Store.
Then Reminders started working normally.
