Hi,
I bought GoodTask for iOS and I'm testing it with the Mac app and everything seemed to be working fine till I added two reminder lists that are being shared with another iCloud user (also using Goodtask).
I'm the "owner" of booth lists and while the first one sync without any problems, and it seems to update in all devices from both users, when the second user tries to clear an item it just doesn't clear and appears again.
In the second list things are even more complicated and it is not syncing anything between users.
Is there any limitation regarding the use of shared iCloud reminders?
