Now when i click to AI Chat and open the file, the file will display at right hand side. I want to always open to left hand side
This is because you have the Chat open as an editor! If you close it, then use the icons in the top right to reopen it (or the keyboard shortcuts), it should re-open as a Pane and editors will not longer display within the same section.
I just came across this issue as well I think it’s bcz I was playing around and tapped “Open chat as Editor”. All you need to do is tap the three dots again and select “Open as Pane”
