Thank you for taking the time to visit the Community to report this issue although, I apologize that you have not received a response.
I would recommend signing out and signing back into the Quicken program. To do this, please follow the steps below.
Go to Edit > Preferences > Quicken ID & Cloud Accounts
Click sign in as a different user
Type "yes" to sign out
Sign back in using your existing Quicken ID
Once this has been completed, please attempt to update once more and let us know the results.
I don't have 2 step set up and it the account is set up as Linked to checking. I don't get an error, it updates the other accounts, but not the cash/checking. I attached a print screen (cleared the account #), there is no online tab. I'm sure it has something to do with it.. Thank you
More info. The investment account is set up for online services and the balance does update. I unchecked it in the Mobile/Web and re-checked and still the cash account does not update. I'm about ready to cancel Quicken and see if I can find another software. I always loved quicken, but I've been trying to get this addressed on and off for approximately a year. Maybe it just doesn't work correctly with Fidelity Investments. Thanks
