This morning 5/12/23 I ran a One Step Update (OSU) on Quicken Premier R49.29 with my bank (US Bank). This resulted in several problems, as described below. I then restored from a 5/10/23 backup, this went fine, and I repeated the OSU with one change, which was successful. Details follow.
My advice to avoid all this: if you are presented with a request to re-authorize your accounts at US Bank, select "remind me later" rather than approving the request. If you want to reauthorize anyway. make a fresh Q backup before allowing it.
Details of what happened:
Prior to all this, my accounts except one were all enabled for "PFM Direct Access" which I understand is being phased out. So, I was halfway expecting a change to my OSU access.
At the start of the first update attempt, after the update began I was asked to re-authorize my US Bank accounts for Quicken access. I clicked OK and was routed to a US Bank site and entered by my usual US Bank browser logins. The next screen asked me to re-authorize Q access to each banking account individually. I did that. I was then returned back to a familiar Q screen which listed each bank account and asked whether I wanted to link Q to that account (I approved those). In some of my older accounts, it did not offer an option to link but an option for some other action, or option to do nothing which is what I selected for those accounts.
I then ran OSU again. For some accounts, all looked OK. I also had several problems: (1) transactions on a credit card going back two weeks were instead downloaded to be added to a CD. I had downloads set for manual confirmation, not auto entry to register. (2) my savings account balance was nearly double the correct amount, the starting balance had been changed, (3) the balance in my two CDs was doubled by means of a duplicated transaction from when I set them up in March (4) they gifted me with a new savings account which had a balance very close to the true balance in my 40-year-old saving account (I rejected this gift). The accounts where I selected "do nothing" were not affected.
I called the US Bank help phone number, but their Q support is not staffed outside normal business hours, apparently on west coast time. I'll try again later.
I began correcting my accounts, but the damage was extensive. I also had a two-day-old backup. I decided instead to restore that backup, which worked fine. I then attempted again a OSU, but instead of allowing the requested re-authorization, I selected "remind me later". The OSU proceed in its normal familiar way, and I had no further problems. I assume "Remind me later" is not a long-term solution, but it works for now.
