@mester98912 During the Cross Progression update process, the team will identify what is referred to as your primary platform. This is determined by the highest level reached across all of your platforms. Content and Apex Coin balances will be associated with this singular account going forward, only the stats (i.e. progress) of this primary platform will be retained. The stats/progress of the other platforms will no longer be accessible.
For players who have multiple platforms with the same highest level: your primary platform will be the one with the highest level that you last logged in on.
