Coming August 30 -- switcher feedback

Wouldn't you love to know why your users are switching to Classic so you could nip any pain points in the bud? Now you can! Starting tomorrow admins can set up the Switcher feedback to capture real-time feedback.

This is a feature that was developed by Salesforce during our internal Lightning transition. It's simple and gets the job done. Check it out!
