Bug Blog: GoToWebinar Freezes After Unmuting
In the GotoWebinar app for iOS, if a moderator unmutes people it may trigger the app to freeze. This has been fixed in version 220.127.116.115, which is available in the App Store.
If you are the GoTo Meeting app, there is also a new version out, that has some unspecified bug fixes. That one is version 18.104.22.1685.
