I finally caved and updated my iPad from iOS 12 to 13.2.2 last week, thinking that enough bugs had been fixed by now. I didn't "upgrade" the reminders app, since all my other devices are still on iOS 12 or Mojave. Anyway, I have a reminder from October that persistently shows up. I delete it, and it shows up again every day. Anyone else have this problem and know how to remedy it? The reminder isn't on any of my other devices.
