There is the following grammar I found (while also getting it from TRY! N2 book) ったら that doesn't have a block with mastery and option to add it to my schedule.
See the screenshot below:
Is it some sort of limitation for this specific grammar or a bug?
Might be the case that it was a community-suggested grammar which causes such behaviour.
It's simply that we do not have quizzing material for it. We've got it for about 98% of the grammar in the system, but not on anything added in the last year or so (with was...maybe 15 or so expressions).
I suppose the quizzing material is some unique one, that is made available only from your side? No community open option to ingest the materials, right?
