Hi everyone,
If you're having issues please feel free to reach out to Feedback@tapas.io.
Also, please note that you have to use the ad that is found at the end of the episodes mentioned above.
If you don't use that ad NCSoft won't know to give us the ok to award you the coins. So don't just go download the game, you have to use the ad provided to get there.
In addition, if you used the ad, downloaded the game from it, and still did not get your coins, please try logging out of Tapas and logging back in.
But if that doesn't work for you feel free to reach out to us at feedback@tapas.io
Thanks!
