Mobile Security Active Armor Invalid email?

Hello @Nilokeras, we understand the importance of setting up mobile security on your device we can help you with your ActiveArmor app.

A common reason for the invalid email error is an extra space after your email address is entered in. Backspace after your email address to ensure that there is no extra space after. This may also mean that a Software update is needed for the device. 

1. Go to Settings on your device and tap General.
2. Tap Software Update and make sure you have the latest version. If you don’t, update it now.
3. Close settings and open the App Store.
4. Tap Updates, and select Update next to AT&T Mobile Security app.
