JoinTTS -> OPM -> Monster flow is confusing

[afeld]

Just got feedback from an applicant that the flow between systems is a bit confusing:

This is what the web http://usajobs.gov page says "You will leave USAJOBS and be sent to the Technology Transformation Service application system once you select "Continue to Agency Site."

When I click "Continue to Agency Site", I'm sent to an archaic looking monster US GSA website with on pithy error message "We were unable to complete your request at this time."

Presumably this is how it's meant to work (minus the error message), as indirect as it is? If that's the case, might be good to lay expectation out in the application documentation, or a "here's what's about to happen" in the How to Apply section of listings.
