Fidelity brokerage not syncing despite going through many troubleshooting steps!

My Fidelity account is not syncing accurately with Quicken. Upon connection reset, it syncs properly. But subsequent new trades at fidelity are not being captured in quicken, even though quicken claims that the accounted is "updated now". I have already been through the connection reset approach to try and fix. Any other suggestions? Many thanks!

I have also tried this suggestion - it did not fix the problem. https://community.quicken.com/discussion/comment/20248374#Comment_20248374

Any other suggestions would be most welcome!
Thanks.
