When I try to agree to the Terms of Use, I get a 403 Forbidden response when connecting to the REST endpoint.
The error shown in the product is below:
Apparently, Quicken has been having trouble with their servers, and the Billpay service provider service was down as well. It appears to be back up today, however, in my case I have to re-enable my accounts for billpay by doing the setup as when I first set it up. Good luck!!
I had already re-enabled my accounts. This is just to accept the terms and conditions of the feature.
