You can see from the screenshots below I am viewing the same exact message. Light mode is on iOS mobile, and dark mode is on desktop.

The comment on mobile shows up as empty. Even if I click on it, the text does not show. The odd thing is the data is still there, because if I hit submit, it sends the data through still and works as if the comment was there.

(Filling out the following with as much detail as you can provide will help us solve your issue sooner.)
