**Description** When a participant reconnects to a session, the dashboard increases the user count, even though it’s the same participant. **Is this a typical Zoom behavior?** **Will Zoom include these users in the billing count?** Hence, the calculation would be as follows: 04:33 - 5 minutes 6 users R$ 0.0159 per minute 6 x 5 = 30 minutes 30 minutes x R$ 0.0159 = R$ 0.477 **Which Web Video SDK version?** 1.10.7 **To Reproduce(If applicable)** Steps to reproduce the behavior: 1. Connect to a session 2. Disable the internet connection 3. Enable the internet connection 4.

How are you rendering the videos themselves? Is this your application, or an example app? When a user leaves a session (or loses internet in your example) they aren’t removed from the session completely - which means it could be possible that on reconnection if they are reconnecting to the session you would have a duplicate user. in the meeting. You may be able to use something like “connection-change” event on reconnection (not sure if it fires on reconnection or not. ) [VideoClient | Zoom Video SDK for Web - 1.10.8](https://marketplacefront.zoom.us/sdk/custom/web/modules/VideoClient.html#on) The other possibility is to remove them from the session on connection loss - which is a parameter for the `init()` method named `leaveOnPageUnload` - here are the docs for that - [InitOptions | Zoom Video SDK for Web - 1.10.8](https://marketplacefront.zoom.us/sdk/custom/web/interfaces/InitOptions.html) Let me know if this helps. ---

Hi Kelly, my question it’s not about the participant “ghost”, but it’s about the duplicated users sessions in Zoom dashboard and how Zoom calculates the meeting cost. The cenario above happens when the client-6 reconnects from the session manually, but the Zoom threats him as a new user. How much would be the session total cost? ![Captura de Tela 2024-05-02 às 11.46.30](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/3/a/3a3810e6ea8089dc2078dd6334d6cec0971ce6c7.png) ---

Sorry for the misunderstanding on my part. I’m not 100% sure how the sessions are billed myself - but would also like to know - I will see if I can get the proper answer for you. Thanks for clarifying. ---
