Content creation

For "fill in the blank" question, if I want to ask a question like:

45 * 2 = <blank>

Then I need to type 45 * 2 = *90*

However, the multiplication sign * has a different meaning here so it doesn't work. Is there a way to get around it (like the escape character)?

Also, I have to use the asterisk as the multiplication sign, and cannot replace it with x or X.

Thank you!

When on my Phone the crossword is not working correctly. The letters dissappear when filling in the words.

Usually, when I wish to replace a filled drop zone with another word, the content does it normally.

However, in the mobile option, a pop-up shows up saying "Are you sure you want to reset this drop zone?"

Why does this only happen on mobile? Is it possible to opt in/out of it?

Thanks in advance!
