GPT 4 in ChatGPT is down? I can't send any prompts to it

I’m trying to prompt GPT 4 in ChatGPT interface but the prompt is not going forward. Neither the Custom GPTs nor the plugins are working.

GPT 3.5 is working. Anyone else facing this issue?

I am having the same issue. No prompts to anything but GPT 3.5. I’ve tried text, files, and photos. Nothing seems to prompt GPT 4.

Earlier today it was working great. This just seemed to happen.

GPT 4 is working on their app though.
