I'm new in this platform, so I can't comment about the new changes, but editing my teacher profile in the Courses tab I have an option for instant Tutoring.
Instant Tutoring is only available for teachers who are familiar with the italki teaching system. You need to complete 5 lessons before your Instant Tutoring privileges are activated Learn more
If you have not completed 5 lessons and would like to offer Instant Tutoring. Please apply for this.
