you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. Are these any specific type of accounts or are they at random? Are they selected inside your Quicken mobile and web section? If you haven't already I would try to reset the cloud.
You can do so by going across the top to edit > preferences > mobile and web > reset your cloud data. Once you've done this see if you're still experiencing issues.
Let us know how it goes!
