I noticed that two chats that I had marked as preserve had been deleted.
In one of the preserve chats, only the first query was left, but none of the others, and a day later it was completely lost.
If I select “preserve”, the chat will be reliably preserved with all its content.
I think it's good that there is a function to delete chats, because a lot of it is just needed briefly. But sometimes you want to keep something because you want to use it over a longer period of time.
