APEX account
After link to EA account in PS5, my apex becomes level 1? How to fix it? @EA_Mako
This sounds like you linked your PSN to a different EA account. This will cause your progress to be lost.
You'll need to re-link the PSN to its original EA account to try restoring access to this progress. Please see the below information.
