Why is my Gmail not syncing on iPad Air 5?

Google have, until recently, used App Specific Passwords - but have now changed their authentication protocols to require the use of OAuth. Simply deleting and re-adding your Gmail account using the Account Wizard should apply the correct authentication method for your Gmail account.

• Delete account:

Settings > Mail > Accounts > [Your GMail Account] > Delete Account

• Force restart the iPad:

Force restart iPad - Apple Support

• Add Mail Account:

Settings > Mail > Add Account

NB: For iOS/iPadOS 18.x, the path to Mail settings is slightly different:

Settings > Apps > Mail > Mail Accounts >

After deleting the account, perform a forced restart before re-adding the email account to your iPad.
