I have multiple accounts with ETrade, all under the same userID and password on their site. Starting about a week to ten days ago, Quicken stopped recognizing how the accounts on ETrade's site linked to the accounts I have (and have had, for many years) in Quicken. When I go through the process of resetting the problem accounts' web access (they're using Express Web Connect), Quicken will first tell me that ETrade's site is asking for additional login info and ask me if I use 2FA. I chose "no", then Quicken finds all my accounts at ETrade but for most of them won't let me choose how to link them to the accounts I have in Quicken. Instead, where you would normally choose "link to existing account →" I just see "Do Not Add to Quicken". I cannot change that.
So, something broke here recently, I assume it's related to the problem that's been ongoing for a week or so with onestep updates in general.
