I just installed iOS 13 public beta and when I went to use the reminders app it asked me to update now or later. When I updated the reminders on all my other devices, iPhone 6, iPad mini 3 and MacBook Air all disappeared 😟 Not happy about this because none of my other devices will be getting an update.
iOS 13 reminders made the reminders on my other devices disappear
That's why I don't use my "real" Apple ID with beta devices. I have a test Apple ID. I don't need beta software screwing up my iCloud things or wallet.
