Hey,
the fill-in-the-blanks-text+ 1.15 is no longer showing the requested fields […] if these are hidden by square brackets [+]. It used to display the ones, that I’d have to answer in red […]. So that I know what to answer. For better understanding, here are some screenshots and the card content:
Card content:

Thats not a [[{{c1::fish}}]].

What it should look like:
I upgraded my computer to an apple silicon one and installed Anki version 2.1.56 for arm64. On my previous system with Anki 2.1.54 for Intel everything works fine.
The only thing that comes to my mind is to delete the square brackets in all the different cards c1, c2 etc. for the blank that is asked manually. But I have a deck with 7k+ cards… 
Maybe someone knows just the right thing to do?
Cheers
