My account level and items and heirlooms have been reset

Hey @foxinmana,

It looks like your post just matches what you had included as a title, but please keep any additional posts in English on these boards, thanks!

This account has never launched Apex Legends before, so if you had played previously that appears to be on a different account.

I do see a Steam account was just linked here, but keep in mind that progress is stored on the EA account level, not on individual platforms like PlayStation, Xbox, Steam, etc. This means if you link your platform to a different EA account, you'll lose access to that progress.  

If you previously played on Steam, you will need to re-link your Steam account to its original EA account to try recovering access to any missing progress.
