Usually, E-1106 automatically pops-up while browsing the Application. This error code only means that "Authentication failed". No need to worry as we would just need to logout and login back to the Application.
To do so:
1. Click on the gear icon on the upper right hand corner.
2. Click on "My Account".
3. Then "Sign out"
4. Log back in using the same phone number linked to your account and you are good to go!
