Thanks for trying this out.
If you're having any issues please email us at firstname.lastname@example.org
A few quick things to point out:
1) You have to be in the US and have either iOS 11+ or Android 6+ to see and/or participate in the offer.
2) You need the newest version of Tapas on your phone.
3) You can't have had FFXV on your phone before.
4) And you have to download the game immediately after going to the App or Play store from Tapas. Don't click away and then go back and download it because they won't see that you came directly from Tapas and won't tell us to give you the coins
5) After downloading the game and getting your Citadel to level 2 make sure to relaunch Tapas. Don't just go back to Tapas.
But if you've done all those things and are still having problems please hit us up at email@example.com and we'll look into it.
Also, our daily limits are reset at 4pm PST everyday.
