I can not find Final Fantasy XIV Beta test on NA PS4 store, but already found it on JP PS4 store since 2-3 days ago. So I wonder if this is limited to JP PSN account only?
I tried downloaded the one from JP PS4 store, it work properly, but able to play only when I use my JP PSN account. On the other hand, I have PS3 version on my NA account and NA PSN, so I prefer to continue using my NA PSN account more. However, when I try to played the beta test that I downloaded from JP store with NA account. it will always give message "please register product code".
