If I edit something pasted from another document within Logos, enable editing, highlight text, mark as fill-in the blank, it appears to work - text with underlines. However, when I enter into Handout mode and select "Hide answers", the answers in the pasted text remains while all of my own text hides as it should.
Interestingly, the text remains on screen but is gone in exporting.
I suspect this may be a bug. I am unable to hide text for handouts from any copied text.
My only recourse is to manually type in what I would otherwise paste. Then I have to add the reference myself as well. Quite time consuming.
