I completely agree with what philipma1957 said. I also took a refund. I can only say that I was almost crucified on GPUHoarder Discord (by all the people posting) when I kept asking to see SQRL Miner and test it before Acorn was released.
You were "almost crucified" not because you asked, but because you never stopped asking at least daily, along with a dozen (or more) others, sometimes only a few messages above yours. Then you kept asking after you requested and received a refund. After a while it gets old.
Perhaps if others insisted to see SQRL miner and it had been released, we would have known earlier about the problems. It is still not out. I am surprised that you think that it is normal.
On another note (although related), have you seen this video?
