Select the 1Core Class App icon from your mobile/tab device to open the app. 

After you logged in, the app will check your device's time zone information. If there is any mismatch between your center's set time zone and your device's time zone, you will get this warning message. 

You can ignore the Time Zone mismatch by selecting the 'That's fine! Let me Proceed!' option or you can select the 'Show me how to fix it!' option to learn how to correct the time zone mismatch.

Selecting the 'That's fine! Let me Proceed!' option will take you to the dashboard of the 1Core Class App.
