Apex legends matchmaking not working after getting unbanned

Here's the same text without bullet points:

Before posting here, I went through pretty much every troubleshooting step I could find, but nothing has fixed the issue.

I've restarted my PS5 multiple times, completely closed and restarted Apex Legends, power cycled my router/modem, and confirmed my internet connection is stable. I've also reinstalled Apex Legends, switched between multiple different data centers (Frankfurt, Amsterdam, London, etc.), and tried matchmaking in every available playlist, including Battle Royale, Ranked, Mixtape, and Firing Range.

I've tried queueing solo, verified that my EA account is correctly linked to my PlayStation account, and waited 5–7 days after my account was unbanned in case the changes needed time to propagate.

Despite all of these troubleshooting steps, the issue is exactly the same. I can log into the game normally, access the lobby, customize my legends, and play the Training mode without any problems. However, every other mode gets stuck in matchmaking indefinitely. Battle Royale, Ranked, Mixtape, and even Firing Range never load into a game. In normal playlists, the player count doesn't appear at all, and in Firing Range it only briefly shows 1–3 players before never loading.

At this point, I'm fairly confident this isn't a console, network, or installation issue. Since the problem only started after my account was unbanned, it seems more likely that my account still has some backend matchmaking restriction or wasn't fully restored after the ban was lifted.

Has anyone else experienced this after being unbanned, or does anyone know if there's another account-side check that EA Support can perform?
