I have 4 accounts at Vanguard. 3 of them update just fine in One Step Update (Quicken for Windows), the 4th, an IRA, hasn't updated in OSU for a couple of months now.
As a temporary solution, I've been able to go into Vanguard directly and downloaded a QFX file to manually update. That is fine as far as it goes, but less desirable than OSU. The manual QFX update also produces a reporting anomaly - see next paragraph - which or may not be relevant.
The reporting anomaly is — say the problem account had 6 transactions in the prior month, which I manually updated via QFX on the 1st of the next month. A few days later, I run another OSU to download new activity in my other Vanguard accounts (OSU is set for all 4 accounts) — that new OSU Summary will report a count of new transactions that is 6 more than the actual number brought in by that OSU - i.e. continues to report as "newly downloaded", the 6 transactions for the problem IRA that I already added via QFX on the 1st. The extra 6 is just a count shown in the interim OSU Summary - not actual "Downloaded Transactions" in the problem account's register.
Even if that anomaly is inconsequential - I still can't update this one Vanguard account with OSU.
This problem "feels to me" a lot like the Vanguard mess earlier this year in
which affected me as well, but since resolved. However, now I'm NOT getting an OL-295 or any other error message - it's just that the one account at Vanguard doesn't update.
I also looked with interest at this thread
and I carefully followed all the steps in @Jim_Harman's helpful post
but unlike others, this didn't fix my problem.
Any help appreciated!
