LOL, nope 
I also didnāt see a link on the Zwift page to the Youtube content. Iād think those things might be best served being displayed pretty prominently on the company website. Keep them hosted on Youtube, but display them here.
And looking at the videosātheyāre kinda messy. There are a lot of short vids about very specific issues (cassette type, for example). But thereās no clear starting point. Does the 1:37 āwhat you need to rideā video, with pics of devices, explain the companion app in enough detail (I donāt think so). Those vids are something of a shotgun approach. Links to two or three foundational videos on the Zwift site would help a lot, I think.
