Hi, really appreciate the response, and reassuring to know we weren’t missing something too obvious 🤔. Thanks also for the suggestions, will follow up, and having started this, think I now need to stick with it for the rest of the week, even if I might be in a bit deep here...

Second that, just taken a look at the video and thanks for the pointers - looking forward to chapter 2.

Glad it's not just me! Have rewatched video a couple of times and am digging around in the various files on Playgrounds but definitely need a bit more of a push in the right direction. The principles discussed all make sense in terms of needing to apply labels, but where to do that and turning theory into practice is proving challenging!
