I have been unable to save the GPT for the last 5-6 hours

I have been unable to save the GPT for the last 5-6 hours. It has been disabled for me. I thought it was due to limited access to GPT-4. Nevertheless, my regular chats with GPT-4 are normal. Why is this happening? Are there any restrictions on the number of GPTs that one user can create?

Does your GPT have Actions? If so, try deleting and re-creating them. That fixed it for me in the past. See this post.
