I was looking at this thread
I have a similar issue when switching back from EWC+ to DC with Fidelity Investments and NetBenefits which I am trying to do because of the failed migration to EWC+
When switching back to DC (zzz-Fidelity Investments DC and zzz-Fidelity NetBenefits), it switches the accounts to Simple Tracking and, as with the referred thread, incorrectly states that the account is using EWC and that this is why Complete Tracking can't be used. The only way to get Complete Tracking back are to deactivate and enter transactions manually, or to make a template copy, which does allow Complete Tracking with the same accounts, but that requires reactivating all my accounts.
Why does Quicken say the account is being managed using EWC when it says in Account Details that it's Direct Connect?
