I suggest resetting your Quicken Cloud, however, I advise that you save a backup first, then sign out of your Web/Mobile applications, then reset, then sign back in. You may follow the instructions below in order to reset the account. However, before doing so, also verify that the Dataset name and the File name match each other identically by navigating to Edit > Preferences > Quicken ID & Cloud Accounts (see below).
If they do not match, please click Edit dataset name and change the Dataset name to match the File name exactly the same (do not copy the file extension: ".QDF").
Then, click OK in the preferences window and proceed to save a backup (just in case). From there, please follow the steps below to reset your cloud data.
