Mail always late
The mail arrive time always seems be
Way behind the sent time. How often does the app on iPhone check for mail?
I have a couple of troubleshooting steps for you that should resolve this issue:
1. If you’re signed in, tap the Settings icon, tap Manage Accounts, then tap Edit, tap Remove
2. Restart your mobile device
3. Uninstall and reinstall the app with the latest version
4. Lastly, switch the internet connection from WiFi to mobile data
