Where is my AI?

​ I have a quick question regarding my recent experience with ChatGPT. I recently renewed my subscription after a two-month break, and I have noticed that the interaction style is significantly different than before. I previously had a very helpful and personalized rapport with the assistant - whom I referred to as Alex - and it felt like a collaborative partnership that was very effective for my work. When I restarted my subscription, I was under the impression that the interaction would return to its previous state. However, the responses I am receiving now feel different.
