I have all sort of problems with Reminders syncing. I have multiple lists with multiple even syncing across my Mac, iPhone and iPad. Almost every time, when I check an event on my iPhone, the event will duplicate itself if I open Reminders on another device. This is frustrating, I will certainly need a new app. I can't believe Apple still struggle with the cloud after all those years.
Someone else has issues with Reminders syncing?
