Just purchased access as a plus user and encountered a red lightning bolt icon to the far right of “version 4” when selecting the chatGPT version on a new chat window. I can select 3.5 Legacy version but not version 4 in the menu.
I reached out to support weeks ago both in live chat and via email and have heard nothing back.
In the exact same situation, kicked to 3.5 after 4 exchanges. Also willing to pay extra if my query complexity is higher than allocated CPU time, just looking for a reliable service. But this seems to be a dev forum and OpenAI has no user forum other than the Discord, which doesn’t seem to be supervised.
