I'm sorry to hear you're experiencing issues with the backchanneling feature. It seems like there might be a glitch with the setting not being properly applied. To assist you further, could you please confirm if you've saved the changes after turning off the backchanneling feature? Also, have you tried refreshing the API or restarting the session after making the change? These steps can sometimes resolve such issues. If you've already tried these steps without success, I would recommend reaching out to our support team for a more in-depth investigation. Please let me know how you'd like to proceed!
