5.5 xhigh requests going to 5.4

For the past three days 60-85% of my 5.5 xhigh requests have been serviced by 5.4. I’ve double and triple checked that I’m not setting the wrong model. My usage is being drained at 5.5 xhigh rates. I’ve contact support but I just got an AI message back saying “we understand your concern please read the pricing page”. Has anyone else been experiencing this? You can check at: chatgptcom/codex/cloud/settings/analytics#usage If anyone has any information regarding this I’d really appreciate you sharing. It feels bad having my usage draining at 5.5 xhigh rates just to be wrestling with 5.4.
