EVA is not able to fully work if you have an XBox account for Elite:Dangerous. This is because of limitations on Frontier's servers, which see XBox accounts as entirely different to PC/Mac accounts. As a result, they aren't able to provide the details that EVA needs - your location, your profile and the current station's market.

EVA is still able to work as a trade computer, but will need to have the database of systems, stations and prices updated occasionally (using the Nav tab).

At the time of writing, the Playstation edition of Elite:Dangerous has only just been released. It is currently not known whether EVA will be able to work fully with the Playstation version, but I would assume that it will be restricted in the same way as the XBox version is.
