Crossword content on tablets

Hi,

wondering if this is just me or other people having this problem

I have created two crossword puzzles which work fine on my Windows 10 destop machine.

However when I tried them out on my Android tabletusing Firefox, they were unusable. I could not enter any input into the squares of the crossword. I would apparently select the square and then hit the letter I wanted to insert, but nothing happened. It did work in Chrome.

On borrowed iPad it worked OK, although order of presentation of clues is reversed.

Using

h5p in Wordpress 6

Tablet: Samsung 6 LE with Android 12

Browser:  Firefox 101.2.0

Just me or are others having the same experience?

Thanks
