If it makes you feel any better, it was a pain in the ass to write it down on mobile too. I had to rearrange tweets every time I've added a new one, and then when I published it, they were suddenly all in a different order than the one I've set up. So I had to edit them from the desktop. And I've failed multiple times to edit the description (both on desktop and mobile), so it remains "I'm this moment" instead of "In this moment" in the description of the moment.
