I've been holding a ETF security (VXUS) for quite some time and have had Quicken updating historical price regularly. Just yesterday I noticed that some of the closing amounts Quicken downloaded are not correct.
The attached image shows the actual closing price according to Yahoo for VXUS and those downloaded by Quicken also for VXUS. Of the 7 days shown as examples 4 days are incorrect and 3 are correct.
I've tired deleting all historical prices from Quicken and redownloading however the same incorrect prices get repopulated.
