Not showing Azon Prime membership?

I bought Amazon Prime last year. We used it the whole time on the Playstation 4. It worked there. You could watch all Prime films for free. Now I wanted to try it on the laptop / mobile phone, but when I log in with my account it says "Try Prime" they think I don't have Prime, but I pay and it works on the PS. Besides, my watchlist is empty. I would like to use the advantages of PRIME, but that is not possible. Can someone help me?

Sounds like the wrong account.
