I have updated to iOS 13.1.2. My phone is iPhone 7. Here is another Reminders problem: Reminders set to repeat monthly, daily , hourly sound a notification at the first set date and time, but do not repeat. This applies both to reminders. set before updating to iOS 13 and to new ones. I read somewhere that turning Reminders off and on again in the phone's Settings > iCloud might fix this, but it has not fixed it in my case.
