Causes
Offline Login Conditions and Validity Period
To use offline mode, you must first log in successfully at least 1 time while online (Wi-Fi) on the tablet to synchronise user authentication information and the vehicle model master DB to the device. Offline login is blocked if there is no record of an initial online login on the tablet or if the user differs from the initial login user.
GPMS offline login is valid only for 72 hours after online login.
Single-Session Principle
Under the single-session principle of 1 account per 1 tablet, security policy blocks simultaneous login on multiple tablets with 1 ID. When you log in on a new device, the authentication token on the existing device expires.
Account Lockout Conditions
The account is locked after 5 incorrect password entries, and entering an incorrect password even after 1 hour immediately locks it again.
Supported Device Restrictions
The PDI/GPMS app is exclusively for officially approved Android tablets, and personal smartphones are not supported.
Solutions
Preparing to Use Offline Mode

Vehicle Model Download Failure During Prolonged Offline Use
Resolve this by logging in again online.
Using Accounts on Multiple Tablets
Obtain and use separate accounts for each operator/tablet.
Unlocking an Account
Use the function on the login screen to send a temporary password by email, or request a password reset from the corporate administrator.
