ChatGPT does not remember any previous answers within a same thread

I recently upgraded to a premium account, and as soon as I did ChatGPT started to become worse and worse.

It doesn’t remember any previous messages from a same thread. For instance if I ask “write an IG post about sustainable packaging”, the system creates a post, I follow by “rewrite in a professional tone”, and the next answer has absolutely nothing to do with sustainable packaging, or the IG post it created. Is anyone facing this issue?
