On Quicken R66.18, some Fidelity investment accounts have stopped updating and show zero balances. They updated correctly for years, and I don't know why they aren't now. When I edit those accounts, it show they're not set up for online, so I go through the online setup process—-connect to Fidelity, jump through their hurdles, and everything seems to be fine. But I've repeated this three times, and still no update.
What should I try next?
