When a card gets copied, everything gets copied : due date, reminder, tags, members,... I checked this by opening the copied card on the desktop app. Everything is there.
When I open the same card on the iOS app however, everything is the same but the reminder : it is turned off. Even if I have an active reminder on the original card and the copied card on the desktop app.
To sync it with the card on the desktop app, I have to open the card on the desktop app, open the due date panel and close it by clicking "save". I don't have to change anything from the reminder menu, just open it and close it by saving it again.
Is there a way to have reminders sync automatically? Is that a bug?
