Anybody else noticed that ChatGPT never uses memories, about me, or instructions anymore?

Literally everything in "personalization" settings is completely ignored, including saved memories. It never references save memories, it never uses custom instructions (like the name I gave my AI, how to address certain characters, and what I call my life story). It never uses anything I put in the "about me" section. It never uses any of that. And I have noticed that it stopped using any personalization options about at the beginning of the year.
