Can't find information about it at all! So, when I click the buy credits button, it just opens the Uplay interface and nothing else happens. Some people say, I need to put money to my Steam wallet but it didn't help. How do you even buy them? Please help.
I found a fix for buying credits in-game:
Open up Uplay before starting the game and go to SETTINGS.
Under GENERAL uncheck ENABLE IN-GAME OVERLAY FOR SUPPORTED GAMES.
Now when you go to the in-game store to purchase credits, your web browser will open to Steam's webpage to authorize the purchase of credits to your account.
Hey ChevalierMinor, glad to hear you found a fix.
