Excellent, I see it working now! Thanks all for being so responsive.
FWIW this is personally my first time using DatoCMS, and I’ve been thoroughly impressed so far. We built this whole client site much faster than expected: every feature we were hoping for was present, we could model everything we wanted (minus a “repeatable” for fields - but Links + separate Models gave us everything we needed there), and the editing experience is amazing (infinite nesting “create new record” modals, with full save/publish experience on each layer, so nice).
We just bumped up to a paid account and are unleashing content editors into the CMS next week.
