Unable to input a chat in GPT 4

I saw one chat on this but saw it was “resolved” even though it does not seem to be an active resolution to this problem. If I’ve missed it, apologies.

I have an upgraded plan and I am unable to insert prompts into GPT 4 or other extensions (DALL-E). 3.5 works fine. By unable, when I hit enter in the prompt window, the prompt disappears and there is no record of the prompt whatsoever.

I’ve tried some of the suggested workarounds (clearing cookies, deleting old chats, trying a different browser or on mobile) and nothing works. Others in my immediate area are able to use GPT 4 on the same network. So it is clear this is a problem for my account.

Any help? Or updates on what is being done from the support team?
