Degradation of Chat quality

I recently took a chance to buy the increased $200 chatGPT subscription. In the beginning everything was working great and I felt amazing about the purchase and the pro-model while it took more time, it was producing amazing responses. but as I continued using the model it randomly stopped sharing the details of what it was doing and the responses often didn’t load. when they did it was less than expected. I am wondering if anyone else is experiencing this? I would love if I could get the model back to where it was on day one when i subscribed. I feel like it might be a usage based issue where we have some sort of token limit that’s undisclosed and after hitting that wall all responses are degraded to save openAI money. Maybe I am overthinking it but this is exactly what’s been happening to me (I’ve been using the plus subscription of ChatGPT since late 2022)
