Got this today from support:

"After Yodlee performed a detailed investigation, what was found is that, unfortunately the software required by the bank, Trusteer Rapport, is not supported at this time.

I would suggest reaching out to the bank to see if they have future plans to have their software compatible with Yodlee integration for third-party apps such as our FENXT bank feeds."

It sounds like Blackbaud is not going to support SunTrust and has put it back on the bank.
