Unable to receive emails after changing Gmail password on Apple Mail

If the Emails is not updating or fetching after changing the password then ensure ur using the emails account settings into the iOS and not the gmail app, and go back into the settings and email then accounts and remove the email address from ur phone , then make sure the updated password is also updated into ur passwords . Sometimes the system will automatically sign u into the old password based off old habits so it’s best to remove the email account all together and make update the passwords and then sign back in and add it back to your accounts And turn the fetch data on

try turning off the wifi and trying it

or turn the wifi on and try again
