About a month ago I reached out to support due to cross save issues. My issues and request were as follows:
I can no longer trade with any Playstation players, regardless if they have enabled cross save and cross play - tested both.
My original Playstation forum account is gone; I can only log into my new pc member forum account.
I would like for my in game account to revert back to the way it was, I am no longer interested in cross save, and I would also like my Playstation forum account back.
Support Desk Response:
"To be able to trade with Tennos across platforms, both players will need a Cross Platform Save Account and have Cross Platform Play enabled via the in-game settings."
With such a response, I can only assume that my request was not read, and a general reply was provided in order to simply close the request. Or, perhaps this is a support bug.
These changes have permanently altered my playstation account as I can no longer trade with any of my friends (regardless if they have enabled cross save/play), and my decade long forum account is gone. To make matters worse, the means to revert accounts back were never provided.
Also note worthy: the Warframe cross platform save page did not provide any warning pertaining to the restrictions of cross save, that information is on another page.
So far as I know, this is the worst cross save game implementation. It's difficult to believe that DE actually thought this through and decided it was a good idea.
