does anyone have that problem when you try buy r6 credits on steam and it says something went wrong try again later?
Hello there eurichard, thank you for getting in contact with us.
This issue is known to us, did you try to make the purchase by testing this, with the Steam overlay enabled and disabled? Do you use a VPN by any chance that you can switch off when you make the purchase and does your Steam Store Country match your current location and IP address as well as the currency you are using?
If you have checked all of these options, it may be you have tried to make too many purchases in a short space of time, this may put a block on you purchasing any in game items from Steam for the next 24 hours.
