the email is very glitchy. I have to reinstall the app about once a week to be able to open my mail.
I have a couple of troubleshooting steps for you that should resolve this issue:
1. Clear the app’s cache
2. If you’re signed in, tap the Settings icon, tap Manage Accounts, then tap Edit, tap Remove
3. Restart your mobile device
4. Lastly, switch the internet connection from WiFi to mobile data
After you’ve performed these steps, should you still encounter this issue, please reach out to our support team at firstname.lastname@example.org.
