If you haven't finished a card by its assigned completion date, then the date shown in the Progress Dial will turn red and flash. Once your card has been extended by your Manager, the date will return to its normal black color and stop flashing.
Two new notifications are available for Learners and Managers:
The first Notification will alert you if your own card is late. If you're a Manager, it will notify you if any of your Learners' cards are late
The second Notification will trigger once your card's completion date has been extended and is no longer late.
You can find these new Notification choices (along with all other Notifications) in your Profile.
