Completed Reminders, how to delete?
I have thousands of complete reminders on the reminder app. I have tried to clear out the list and it never works. I looked for a method on the iPhone, and on the app for Mac OS and found none. On iCloud.com there is a way to clear completed which looks like it worked, until i log back in. The list will go empty, i will then log out and later log back in and they are all there again.
Is there any way to eliminate the completed reminders?
Thanks
