By default, pre-fetching is enabled so the app automatically loads new emails in the background, resulting in superior load time for new mail. To disable email Pre-fetching:
- Tap the SideMenu icon at the left of your Navigation Bar to open the Side Menu.
- Tap the Gear icon at the bottom of the Side Menu to bring up Settings.
- Tap Mail.
- Under the Data Usage section, tap the Pre-fetch emails switch to disable it.
Note: Disabling the Pre-fetching feature degrades the app's performance and your user experience.
