When you start a livestream to YouTube Live on the GO:PODCAST app, you may see the error "The user is not enabled for live streaming" within 10 seconds of starting. This means your YouTube channel does not yet meet YouTube's requirements for mobile live streaming. For the requirements, see YouTube's "Create a live stream on mobile" page.
If your channel does not meet YouTube's requirements, select "Custom" from the Streaming Service list in the GO:PODCAST app. Sign in to your YouTube account in a web browser, open YouTube Studio, and copy the RTMP URL and Stream Key into the GO:PODCAST app. For details, see "Manually configuring the destination server" in the GO:PODCAST app Owner's Manual.
