Old Account Stuck: No Match Allocation, Even Firing Range Fails

Dear EA Support,

My old S2 Apex account cannot enter any match. It was created on Origin and later linked to Steam; I now launch via Steam. Standard matchmaking searches forever, Ranked is locked by required matches, and even Firing Range will not load. Firing Range is single-player, so this is not population—my account cannot get a match allocation.

Another account on same PC/network/region works normally, including Firing Range. No ban notice; no violations. This suggests a backend matchmaking or Origin-to-Steam linkage issue on this account.

Account: [edit: email address removed], IGN 一枕明月, Steam (originally Origin), level 4, last played S2.

Tried: EA re-login, language-switch update, Tokyo/Singapore, cross-play on, Ranked cancel + Firing Range, verify files.

Request: Please check/reset this account’s stuck matchmaking allocation state, and verify the Origin-to-Steam linkage is not causing the block. I can provide screenshots/videos.

Thanks, yizhenyue
