If you are using MobLab through MindTap and using the Safari browser on mobile or desktop (laptop), it is important you update your privacy preferences to allow cross-site tracking.
Safari on Desktops or Laptops
In your Safari privacy settings, you'll need to disable "Prevent cross-site tracking". Make sure the option is unchecked in your Privacy preferences menu. If enabled, this option will prevent you from launching MobLab successfully, and you will see an error message or a login page instead.
Safari on Mobile
Likewise, in order to successfully launch from MindTap to MobLab on the mobile Safari browser, you need to update your Privacy & Security Settings for Safari. Go to Settings > Safari, then scroll down to Privacy & Security and toggle it off "Prevent Cross-Site Tracking".
