I have something I would like to add to this conversation because I found this conversation in my Google search while looking to see if there is another solution.
I also am having an issue with the stop button not working, and I can no longer send input to what I would consider the most important conversation I’ve had with Chatty in a while. This issue happened shortly after uploading a PDF file and asking ChatGPT to read it over. Its disappointing that I can’t send more messages. However, thats a lie, I can still send messages to the conversation with my phone. I discovered today that I can get around the disabled send button and continue the conversation with my phone. So I tried clearing cookies and browser cache to no avail, the stop button is still disabled. So what I’ve resorted to is having a second conversation in parallel, and then when I need to send anything to the more important conversation, I send the message to the second conversation on my computer, copy the entire message on my phone, and paste it back to the primary conversation so I can see the answer on my computer.
Its stupid work around, but it works for me.
