The pre purchase of EoD gives the shared intentory slot now or at the expansion release?

For those who already pre purchased the expansion: the granted shared inventory slot is already provided or a feature unlocked when  End of Dragons arrives?

Now

And does that make you able to have 25 shared slots ?

 

Until now I bought all the shared slots I could, but the limit seems to be 24.
