Membership Pro 2 - Attributes add-on missing files

I am trying to add membership attributes after enabling the add-on but the console reported that the plugin is missing css and js assets. I checked the plugin and there is no assets folder present or any css or js. I downloaded a fresh copy of membership pro 2 from your website, which does not contain an assets folder either, and uploaded it to a fresh instance of wordpress and its giving me 404s of assets in the console and I cannot save any attributes. Please advise.
