My feedback: I like the feature, but I don’t think it’s responsible to release it when it fails to work in all task and project Description fields, arguably the most or certainly one of the most needed and expected places users would expect this work.
It’s an additional problem not to call that out in the Help Center article or announcement of the feature. The Help Center article for Knowledge says (emphasis mine):
Entries added in the Knowledge tab can also be found throughout Asana via contextual hovercards, so users can access consistent definitions across Asana quickly and easily.
This image shows it works in a comment but not in task Description (which my cursor was currently hovering):
Thanks,
Larry
