I see "ONGOING 10/24/25 Fidelity Migration" but no comments in the post that are dated 10/24 (today).
I took some online advice and deactivated all of my Fidelity Accounts in Quicken. Then 1-by-1, I setup the online services for all 10 of my Fidelity accounts. When I was done I was able to run an Update on all my Fidelity accounts without any errors!
The fix was short lived. The next update reported "Connectivity Problems." on all 10 accounts. I am back to where I started with no Fidelity accounts being updated with Quicken.
Now what? Do I just wait for the next post/patch?
