This is likely connected to the Chase mess, the switchover on Amex, etc. But it also has a history.
I keep 2 copies of QPW on different PC's, primary and backup. I do NOT do anything 'mobile' because I know it will badly corrupt my files, as it has in the past on several occassions. Typical symptom - it creates sort of duplicate copies with a new number attached for existing accounts. Like Checking 1, Checking 2, etc. For many accounts. I hide them, in some cases zero out and close. I do NOT have downloads going for any of the bad accounts. Another symptom - Quicken loses track of what bank or account gets downloaded to what Quicken account, just kind of random matching or the above, duplication of accounts.
On my primary, Chase seems MOSTLY correct MOST of the time, now. Amex Card seems to have made its transition OK.
Once every several weeks, I take the time (lots of it) to update my backup Quicken. So far this time it's taken a few hours. Piles of bad accounts popped up, plus I found numerous transactions going to the wrong account. For instance, checking transactions went into Quicken savings accounts.
So, I've mostly cleaned it up yet again, moving numerous transactions to correct accounts, deleting duplicate transactions, turning off duplicate accounts. I'd already emptied and closed out all bad accounts, but now I've got a whole bunch of new ones, that when I have a few hours I will zero out and CLOSE. But this is getting very, very tedious.
In the meantime, after file validation (seemed like a good idea), I've gotten a message - your last online session was not completed… It gives instructions - several, on what to do next. But to do so, you've got to close the error box with the instructions, making it rather difficult to follow those, unless you have photographic memory. OK, I can take a photo with my phone - but I shouldn't have to. Whoever designed this process has probably never had to do it in real life. I spent a pile of years as a financial (banks) software developer, and specialized in easy to use GUI's. This absolutely flunks.
Quicken, how about REAL answers, and REAL fixes to bugs, and some openess as to what's going on. I've been using Quicken a long time, and while it's getting fancier, it's not getting better.
