There is a uservoice that exists that queries some of the wisdom on this. But I can’t link to it at this time
Broadcaster_id’s never change but a username will if the caster changes their name.
But yes this is a “barrier to entry” for non devs.
But a broadcasters tool/website can easily present the URL to users to import.
And/or the broadcaster can link to the iCal URL in panels.
But a user is also not gonna be looking in the docs for iCal anyway
And the schedule page for a streamer doesn’t (currently) link to it which would solve the problem.
So there is no easy discoverability for “non devs” here anyway
