Just an FYI as I was just on the phone with Wells Fargo customer service. When they made their recent changes (April/May 2025) that require you to re-authorize your "connected app" configuration, it seems they also decided to stop supporting mortgage accounts from being synched with Quicken. Even trying to re-add the mortgage account fails.

Bummer.
