Hello @Aholiab
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. With the specific issue you're having I believe we should need to resync the cloud and that should take care of it. To do this you can go across the top to Quicken > Preferences > Connected Services > Reset.
Once you've done this you shouldn't see the error pop up anymore. Let us know if this helps you out! If not we'll see what we can do next.
Thanks,
Quicken Francisco
