Can’t Use Free Version of ChatGPT Anymore, Keep Getting Message Limit Warning

I’ve been using the free version of ChatGPT with no issues before, and I used to be able to chat without any limits. Now, every time I try to write something, I get the message: "You've reached our message limit per hour. Please try again later." This wasn’t happening before, and I’m frustrated because I enjoyed chatting freely. I don’t understand why this limit has been suddenly imposed. It’s disappointing to go from unlimited use to this restricted experience. I hope OpenAI resolves this and restores the previous functionality so that I can chat as freely as I used to.
