Spoke again with WF, which confirms that they do not support My Money, nor do they expect to support a MyMoney QFX in any foreseable future.
During the conversation I asked whether the QFX server associated with WF in Setting Up QFX connection (
https://www.oasis.cfree.com/3001.ofxgp) is a valid address, and was informed that it is used exclusively with QuickBooks. I tried a QBW AppVer and all the AppIds in the Tweaking chart, with no more success than when I used the various Money AppIds.
I guarantee that my password/username are exactly the ones I use to access the WF web site. I would hate to abandon MyMoney over this matter.
