Why am I not able to see the ‘Offline’ button on my standard timesheet even when I have the permission enabled?

Summary:
The Offline button on the timesheet is visible only when the authentication type is set to Web TimeSheet Internal under the user's profile. SAML is an unsupported authentication type.

• Log into Web TimeSheet as the administrator.
• Click on the Administration icon at the top menu bar.
• Select Users from the left pane, under the Users/Departments category.
• Pick the user for whom the authentication type need to be verified or changed to Web TimeSheet Internal.
• Click the Edit button (represented by a notepad & pencil icon) next to the user name or double-click on the user name.
• Click the drop-down next to Authentication Type, under the Access tab.
• Pick Web TimeSheet Internal from the drop-down.
• Click Save.

Note:
Refer the attached screenshot for illustration.
