I have three Vanguard accounts. I had to reconnect two of them. When I reconnect, I am suddenly in Simple mode with no option to change that. That is, the Tracking Method box on the general tab is frozen at Simple with no option to click Complete. (The third account is not involved, still connected for Complete.)
That box explains that Vanguard uses EWC so I can't get complete. That makes no sense for various reasons. The other account uses Direct Connect. Worse yet, the Account List shows these two accounts also as Direct Connect even though I can't get Complete downloads. And the Account Details Online tab shows Connection Method: Direct Connect.
Other info: I tried allowing Quicken to set up new accounts instead of linking to the existing accounts. That works fine — as long as I don't want all my historical transactions. Also I set up a test file and connected Vanguard. All three accounts come in as Complete.
There are some other strangenesses in my Vanguard setup, but they have been that way for a long time while this problem has only started this week. I can get into that detail if necessary, but I think it will just confuse this discussion.
