**Description**  
Session is destroyed when first joined HOST kills the app.

**Which iOS Video SDK version?**

- 1.3.0 - 1.4.0

**To Reproduce**  
Steps to reproduce the behavior:

1. join session with multiple hosts (all users need to be hosts so they can unmute themselves)
2. kill the app of one of the users
3. all users are disconnected - the session was destroyed. The SDK reports the following error:

```auto
{
  "code" : 2008,
  "description" : "Disconnecting to the session due to failover.",
  "name" : "Session_Disconncting",
  "suggestion" : "Please clean up your UI components and try to reconnect to the session."
}

```

@rokgregoric are you calling `zoom.leave(true) `? We had to write some logic to evaluate if it wasn’t the host (or not person the we wanted to kill the session), then we called `zoom.leave()` and passed that empty (without true). Then the session properly stayed active.

As described briefly here: [Reference](https://marketplace.zoom.us/docs/sdk/video/web/reference/)

Under `videoClient > leave `

@parker no … I am not calling `zoom.leave(true)` … in fact I don’t call it at all … since the app crashes / is killed.

As workaround I’ve added a `zoom.disconnect()` call in the `appWillTerminate` callback … just before calling `zoom.appWillTerminate()` and this seems to prevent the problem from happening.

But if the app crashes for any reason (for the first HOST) I don’t have a way to call that.

@rokgregoric  
Thank you for reporting this issue.  
It seems your app crashed when you receive the error of Errors\_Session\_Disconncting(2008), right?  
Would you mind to give us a call stack of this crash issue?  
Thanks

@jackie.chen no … our users are killing the app from the app switcher and when I tried to replicate that I noticed that the session was destroyed if the first joined HOST did that.
