Hello @KevinPL
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering here if we may just need to update the securities individually and that's why we're having issues.
To do this you'll want to go across the top to tools > security list. Click on the securities you're having issues with. At the top see if you're able to update the security. If not select edit details and try finding the symbol and select ok.
Ideally once you've done this you'll be able to get your prices updating again. If not we'll see what we can try next.
Thanks,
Quicken Francisco
