Well I know it says one thing but I will say 2
Request mentoring through the online editor for uncompleted solutions. I know you can request mentoring for unfinished solutions for the local editor. Although for new users that ain’t that straightforward and it is generally a lot easier to work in the online editor, therefore, I believe you should be able to do it.
Also, that mentoring sessions will automatically close after a week if no new chat has been registered. I currently have mentoring sessions for students and they haven’t replied for 3 months. Even if I set a reminder. It just feels like the awaiting student queue will fill up over time. Therefore I would like them to get automatically closed.
