Hi @rehema.zoom
Yes. I checked with VideoSDKUIToolkit and faced the same issue. Then I found that issue happens when using SDK from 1.8.5 to 1.11.2 from 2nd attempt joining session. I reported another issue here
Please try the latest version. Also, please share steps to reproduce the issue and the native SDK logs if the issue is happening on the native iOS/Android SDK.
Also, please make sure you are handling the user updated event listeners so your UI can keep track of the muted/unmuted state.
