Why cant I get coins while watching advertisements？

I would like to ask why ios app（Daohei) clients are unable to obtain gold coins when watching advertisements?

You can watch the ads during the Day.
And at the end of the Day you go to my centre- taxi and you get the coins. Just after 18:00 oclock European time.
Only once a day.

Hi, Caro1970. Is there a way to still download the app? I scanned the code, but I was taking to a copy of the same page I had scanned. Thank you very much in advance.
