My game notified me about unlocking Werewolf perks, but I don't know how to access them. I've tried pressing the journal button and stats button, but nothing happens. I'm on PC.

Nevermind, please ignore this.

Can you explain how you did it? I know you have to be in Beast Form, but if you cannot enter any menus while transformed (except for the journal) how can you see/pick perks? I understand the total amount of people killed will count towards getting perks, but can you choose what perks you want? Or do you have no choice but to max out the tree with every perk?

Found it - in case anyone else needs to know. On the PC, it's the Tab key by default.

Is it the same for Vampire Lords?

yes
