Coach Natalie et al., I was tracking the issue with Vanguard and having to reauthorize and receiving an FDP-350 error. You have closed it as "resolved", however, I am still receiving the reauthorization request with an FDP-390 error. I cannot get it to work when I use the app (Android) or the Simplifi windows webapp. I am able to log into Vanguard directly with no issues. Can someone PLEASE offer some advice as to how to overcome this issue? I thought the now-closed Vanguard/FDP-350 error post was going to resolve it but that is not the case. I did get it to work two weeks ago but haven't had any luck since then. It has been failing consistently for more than a month.
