Can't try Addressables - nothing works!

I am trying to work with addressables to check out the new workflows and give feedback.
As of right now, i cannot seem to do anything!

The package is imported, i am tagging an asset (prefab for example) as addressable and giving it a name.
The "addressable assets" window is completely empty. not sure what i'm doing wrong.

I am on Unity 2018.2 with the 0.1.2 version of the preview package.
BTW, I already reported 2 bugs: 1060509 and 1060522 (maybe they are the cause why i can't do anything?)
but i am not sure how anyone else could work with it if that's the case.

Any help will be appreciated

 

Try reimport the whole project, close unity, open again

 

Reimporting and reopening the project did the trick (maybe only reopening would've solved it).

I wonder how come nobody else faced this issue like me
