PS4 Competitive Tier Not Changing

Despite winning 14 games and being promoted twice, I am still stuck at Bronze Tier 5 (bottom of the bottom).

I currently have a K/D around 4 as a tank, dealing 8k damage and eliminating 22 every 10 minutes. I have earned an SR of 2500 twice previously. I am not a Bronze player.

I hated Overwatch because, as a single player without a group, I got stuck permanently at the bottom with quitters and saboteurs.

It seems Overwatch 2 hasn’t changed.

Maybe PS4s have NEVER been able to increase competitive tier?
