It has been well over a year - you would think that a couple major companies could get together in that time and solve whatever is the issue.
The short version is that back in 2024 - Primerica changed their website for customer access to
https://primerica.accessportals.com/home
and it seems that Quicken has not bothered to update where their software attempts to connect to Primerica.
I have been using Quicken for 20+ years and the main reason I switched to the subscription version was to get the investments syncing function - and that has stopped working.
I did start a post about this about a year ago - and have send multiple repots to Quicken from the app - so not really sure what the hold up could be.
