Error says this for my Schwab accounts today: "We could not find an active account for you at Charles Schwab & Co., Inc.. If you have an active account at Charles Schwab & Co., Inc., contact Quicken care and report this problem. (QCS-0500)"
In the error details it says: "Exception when transforming Holdings/Transactions". There is also a "WCC Code" of CC-569.
