@jackshen the app is not crashing anymore, but when I test it with Millicast Publisher (from dolby.io dashboard) which will use empty sourceId for main source, then there is nothing in our viewer app.
Note: you have to manually copy the streamId and streamName then put them to the viewer app query string.
