Having the slow prescription problem since early May.
Just got off phone w/ AC tech support.
I was told that a recent change by eprescibe caused these delays, and that delays of 10-20 seconds are now considered normal.
I am on 10.0.2, but he told me to expect similar delay w/ 11.0.
So, another new feature!
FWIW, I was told by AC that the information Victor was given is incorrect. We should NOT expect a 10-20 second delay to eprescribe in V11.0.
