Hello @Barry Hu
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. You're not receiving any error and not getting any transactions I'm wondering if we may need to refresh the connection by deactivating and reactivating the accounts that are experiencing issues. I'll leave steps on how to do so down below.
First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.

Next we'll try deactivating all of the accounts. You can do so by following the article listed down below.

Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.

Once you've had a chance to try this let us know if you're able to get your downloads up and running. If not we'll take a look and see what we can find next.
Thanks,
Quicken Francisco
