**Description**  
Hello, we currently have the latest meeting sdk version (5.7.6.1082) installed. But when trying to join a webinar we are receiving the error `MobileRTCMeetError_MeetingClientIncompatible` and message `the mobilertc version is incompatible` for the callback `(void)onMeetingError:(MobileRTCMeetError)error message:(NSString *)message`. Is it possible that this meeting is not supported by the latest version of the sdk? Thank you.

**Which iOS Meeting SDK version?**  
5.7.6.1082
