In one chat, I generated so many pictures and also uploaded many pictures in one chat, but as many picture goes by, the chat became laggy, maybe because it takes too much time to show all its generated pictures in HD. So, it will be less lag if the chat shows the thumbnail version of the picture first, and when the thumbnail is clicked, it will load the full HD version of the picture.
I can’t even start a new chat because it may delete the memory of my current chat (I have to preserve the character design in the chat’s memory).
