Session Replay Integration Issues: Main Thread Hangs on Start

·Jun 09, 2025 07:31 PM·

Hello all, I am trying to integrate session replay into my code base and for some reason, the moment UI hits 'start_session_recording', it hangs looks like the main thread is getting hanged. This is happening very recently, not the case when i was testing before, I am using the latest mix-panel browser version.

Hi there- Julianne from Mixpanel Support here. That definitely sounds unexpected. Can you submit a ticket via our webform so we can further investigate? When you submit the ticket, it would be helpful if you included information about when you call 'start_session_recording', along with a link to your site for testing, if possible.
