The Cognito App Client Managed login pages configuration under Login pages may be reset during upgrade. If you use SSO, record those settings before upgrading and re-apply them after the upgrade completes.
The CloudFormation output AuthApiUrl has been renamed to UserAuthApiUrl. If you have hard-coded AuthApiUrl, update your configuration to use UserAuthApiUrl. If you use the certificate CloudFormation template, update that template before applying the 1.19.0 upgrade.
