Hi Zoom Teams,

* * *

**Description**  
We are facing that block screen issue on iOS. (we did not observe same issue on Android)

The situation is we have two users (one is using Web browser, another is using iOS app)  
When two users join the same sessions, they can hear and see each other (audio functionality works fine) but sometimes iOS user can not see remote user (block screen occur)  
we have check the remote user videoStatus is “on” so we use ZoomView element to display the screen but only show black screen.

Here is the SessionID we used: 3Lxu1sRZSNWKnh1oBuXKeg==

Thanks.

**Which iOS Video SDK version?**  
iOS Video SDK version is 2.1.10

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Two User join session (1 use Web Browser, 1 use iOS app)
2. They can hear and see each other (audio and video functionalities work fine)
3. iOS user leave session
4. iOS user join the same session
5. iOS user cannot see remote user (black screen occur, screen become normal after Web user toggle off → toggle on camera)

**Smartphone (please complete the following information):**

- Device: iPhone 12
- OS: iOS 18.5

Hi Tyrion,

This appears to be a known issue with the Zoom iOS Video SDK (v2.1.10), where video rendering can fail after a rejoin unless the remote user restarts their camera. As a workaround, you can prompt the Web user to toggle their video off and back on when this happens. Alternatively, consider upgrading to the latest SDK version, as recent releases have addressed similar rendering bugs on iOS.

Regards

Hi @anon93533829 ,  
Thanks for reply,  
we tried latest SDK version v2.2.5 and rejoin session show another error

```auto
[Error: Join Session failed]

```

there is no any error code, is it also a known issue for Video SDK (v2.2.5) ?
