What is the red bubble notification on the Jumbo icon for?
If you see a red bubble notification appear on the app's icon, it will mean one of two things:
1. There is new contents in your Vault (either a newly activated 2FA code or newly archived contents). If this is the case, you can get the notification to disappear by opening Jumbo and tapping the Vault icon.
2. You have an alert on your Home screen. These are located at the very top of your home screen. After you have read the alert, you can dismiss it by swiping it to the left.
