[Solved] Redeem a code brought from fanatical

Hi, I have just got the gold bundle from fanatical, but when I go into my profile, the web based or android app there is not a redeem code button, can you only enter the code into the desktop app?

It shows up fine for me on the web app:


Fanatical wrote in their support website a page to explain how to use it.

Thanks, I stupidly could not find the redeem button, all well now!
