However, I've spotted a couple of interesting gotchas:
- The Content to include drop-down in the Advanced setting of the Target editor (the one that arrived in 2020 r2) has vanished. You might want to watch out for that if you use it. I've reported this as a bug.
- The new responsive images with popups don't seem to work (I've built the project from the e-learning and the hotspots go walkabout if you size down: see attached image where the hotspot relates to area 2 and area 3's has vanished of the edge)
