When I'm on the iPad I usually use a bluetooth keyboard. What I've found in both Safari and Chrome (when working on an 'ible, not commenting) is that even when focus is in the text box and the arrow keys or backspace key both work, text entry is not recognized, and no amount of tapping into the field helps.

However, if I tap a different text field, such as the "Title," then tap into the text field, I can resume my typing. It also works if I save, then refresh, then tap in.

So it feels like a weird IOS problem with focus. Extra strange that some keys on the BT keyboard would register, making it look like the focus was correct, only to disallow plain old numbers and letters.

This may coincide with manual saves and auto-saves, as well as clipboard operations.

As I mentioned, I haven't noticed this in comments, only while making an instructable. And I haven't noticed the issue with the IOS on-screen keyboard, because I use a BT one. But it sure sounds like we may be dealing with a similar frustration.

Just chiming in,

Thanks!

This occasionally happens to me, I'm on an IPad almost all the time when I'm on instructables. For me, just tapping the comment box a second time will solve it, but my guess is that you've tried that already.

I can leave comments on an iPad and on my smartphone on both the regular and mobile version of the site. Can you give us more details?
(I did notice there was a slight delay after hitting 'post' to when the comment appeared)

Which part doesn't work? Are you logged in? What happens when you click "Add comment"? Or does it just not post the comment when you click "Post Comment"?
