As of June 30th, One step update acts normally, but no transactions are syncing or downloading. I can see the credit card or checking account posts on my bank websites, however they no longer appear in the account register where they get matched, accepted, or posted. I am running the latest Quicken for Windows (R51.10). No error messages are present.
Note: Only Vanguard works properly. I contacted my bank and they informed me it is on Quicken side as the bank has make no changes to their banking system software that would effect the syncing.
