Hi there and Welcome!
Apologies for any inconvenience caused. We have looked into this further for you with our development team. At the moment, our development team is actually going through a full refactor of the Unity SDK and the documentation itself, so we won't have any new documentation to be able to provide you with at this time. Whilst we go through this whole refactor, which will include various updates and fixes, we will let you know and keep you informed.
I would also highly recommend to check our Enjin Announcements telegram channel for the updates as well, as well as when do have all the necessary updates and changes live, we will be posting here on the forum to keep all of ours users and game developers aware of the latest Unity SDK version.
If you have any questions or concerns at all, please let us know. 😃
