I have not received premium on the test server. Yes, I've used "claim rewards" and have received the founder gear, except premium. I also don't receive premium when I try to buy it with gold.
Same here. Logged in and out a few times too, with no difference.
i guess u should wait. one of our guys had issue with buing prem on the second character
first char use "claim rewards" and recieve prem and other staff after 5 mins
second char tried to buy premium, had -gold, premium comes after ~45 mins
thanks for reporting this. The issue is already known and we are working on it.
