No, our healer tried after. He tried being healer via tool finder only Taral V hard mode as a pug himself using group finder. He was teleported and 3 with more pugs to Taral V, didnt kill everything and got the daily reward after final boss.
Truth be told, this
sounds like the bug, not your situation. If you queue for the group finder and choose specific FPs only out of a tier, then the interface will tell you that you aren't eligible for the daily BH comm reward. You MUST choose random. I went in with a completely preformed group and got my comms as soon as the instance was finished, but we chose any T1 HM flashpoint.
