When are Alphabear Notifications sent? (Mobile Version)

As of version 01.13.03, notifications are sent for the following events:

• When your Hourly Coin Bonus is maxed out. This is the point at which coins stop accumulating--you should collect your coins ASAP when you see this notification so that you don't miss out on coinage.
• When a Verses Mode challenge that you initiated has concluded. You can now claim your rewards and initiate a new challenge.
