Instant lessons are those that learners request here and now. You have several minutes to start or decline them.
You can set the price for instant lessons by going to "Tutor studio" > "Private lessons settings". Here, you can also choose if you want to receive instant lesson requests while you're online and/or offline.
If you don't want to receive instant lesson requests during your livestream:
1. Under the player window, find the block called "Private lessons during stream"
2. Keep the "Allow requests for instant lessons" toggle switch off
