Error message after syncing account to cloud

Hi group,

This just began after the most recent new version download yesterday; never had the issue before.

When I sync my account exiting Quicken I now get this message: The account "Unspecified Bill Presentment account was not synced. An internal error occurred while processing your request."

Why am I getting this, and how do I fix it?

I am on version R64.19; build 27.1.64.19.

Thanks in advance for your help.
