Found this link from December 2021, which sounds like it is a "bug".
However, this is no resolution on that post, and the link to another thread with more infomration appears to be dead. While this isn't a deal breaker for me, Quicken has issued more than a dozen updates since that post last year and yet the problem persists.
To review, the issue is that Quick is reporting mortgage accounts with the credit card (revolving) accounts, so it appears that the credit card usage is outrageously high.
This seems like it would be a relatively easy fix.
Are there plans to remedy this?
