Did you receive any reply from OpenAI? Has anyone else here received any constructive feedback from OpenAI?
It’s been more than a week now; I have not received any reply to my last email.

My 5.5 Pro Extended is still failing and replying through 5.3 Mini.
This is pathetic service.

yes but

useless……

Same issue. Have opened a support ticket. They gave boilerplate. But said: reach out if it continues to happen on brand new threads/chats, which it is/does — so an active support thread.

10+ days and still waiting for a reply from OpenAI. This is pathetic.
Case# 10179682

Just checked — this routing issue doesn’t appear in iOS or macOS, only on web. Also doesn’t seem to discriminate on IP address. I think it’s a Trust/model-restriction bug.

Workaround thus: iOS + macOS native apps for now.

Update: I spoke to soon.

Not True. I used iPad to have a try, not useful.
