I have posted about the subject quite a bit. But I did receive EUA for an upcoming Friday morning flight at 5 day EUA time this morning. This flight had "R" availability before EUA time.

On a later flight I did not get EUA - as expected - since no "R" bucket available and F appears to be sold out.

It appears to me that EUA is working properly now. Did you check to see if "R" bucket was available before the EUA time?
