To reinstate MobileSCAN notifications, log in to the mobile app. Click on the profile icon on the top right corner and select MobileSCAN. 

In the upper right-hand corner is a gear icon. When you click on this, all your MobileSCAN devices will be shown. 

Find your device and select it, then select Reset push notifications. 

What do MobileSCAN push notifications look like?

These notifications look just like other Citadele notifications, but when you click on them, you will be taken to the Citadele app.

In the Citadele app, you will have to confirm this request by entering the 5-digit MobileSCAN code, or biometric such as your finger print. 

After you successfully confirm, you will see that you can continue on.

How do I know if I am receiving MobileSCAN push notifications? 

You receive these notifications when you need to authorise and confirm that it is really you, for example, when you log in to the online bank. When you enter your username, we will send a MobileSCAN notification to your smart device which, when you open it, you can use to confirm your identity by entering your MobileSCAN code.
 

Sometimes, Citadele app notifications stop working if notifications are blocked for the whole device. To reinstate them, go to Settings → Notifications. Find the Citadele app in the list and select it. Ensure that all notifications have been enabled.

Also make sure that your device is not on Do Not Disturb mode. Go to Settings → Do Not Disturb. There, you will see whether this mode is activated.
