An Error occurring again and again

When I pose a second question to ChatGPT, I consistently encounter the error message: “Something went wrong. If this issue persists, please contact us through our help center at help.openai.com .”

This situation is quite baffling. After upgrading to Plus last month, I no longer needed to refresh the webpage after each query. However, merely a few days ago, upon paying for the next month’s membership benefits, I found myself having to refresh the webpage after every question once more. What could be causing this? Is it due to my recent payment and inability to pay further, resulting in Plus users being overlooked?

Despite searching extensively online, I have been unable to find any solutions, explanations, or reasons for this issue. Could anyone kindly offer a solution?
