There is a middle man, the hub. You are not sending directly to the pharmacy, and your confirmation is not to the pharmacy, but to the hub. I get this same problem with a non-AC e-Rx.
Getting it to the pharmacy it the hub's job. You would like to think of it as instantaneous, but I guess they have bottlenecks as well.
Most of the time my texts on my phone go thru quickly, sometimes not.
Patients might need to be trained to call their pharmacy to verify receipt and filled before going there and wasting an hour sometimes.
