To get them in your reviews it is a bit hidden, but you can go to Content → Lessons on the web app:
This was what I was raising really, that it looks like a couple of items had made it into the live system but might not be fully hooked up - for example, the structure details are also missing from the new items - which made it feel like a feature switch could have been toggled on by mistake, and whilst they may know new items are in the system they might not know it is currently possible for users to add them to reviews.
EDIT: Beat me to it - sounds like you found them already. Yeah, I don’t usually do it like that - but I wanted to find the new items.
Hmm, feels like I shouldn’t have been allowed to do this - hints and sounds aren’t present as well:
@Asher Should I have been able to add the new grammar items to my reviews yet? I feel like this might be a bit of an edge case - item added.
