Hi JJReardon01,
Thank you for visiting Apple Support Communities.
It sounds like you're not able to receive email from your Gmail account after updating iOS, but you can send email.
In this case, try these troubleshooting steps from the Support document Get help with Mail on iPhone, iPad, and iPod touch:
- To make sure that you're connected to the Internet, open Safari and go to www.apple.com.
- Log in to your email provider's website to make sure that the account is active and the password is correct.
- Make sure your settings are correct using Mail Settings Lookup.
- Restart your iOS device.
- Delete the affected email account from your device.
- Tap Settings > Mail, Contacts, Calendars.
- Tap the affected email account.
- Tap Delete Account.
- Add your account again.
All the best,
Jeremy
