So I hope this makes sense, as I have hard time explaining it.
On mobile, when I want to make a mention of someone, I start typing in " Username ". The menu drops down for me to pick from a list of names that start the same way as what I typed in. I pick the name, it fills in perfectly. For example, I typed "@usern", and picked the " Username " from the menu. However, if I continue entering my message, it will disregard the name I picked, and continue typing as if I never did. So, say, I wanted to type " Username hello there!", but since I pocked the name from the dropdown, it will become "@usern hello there!"
A way to avoid it, is pick the name you need, then place the, uh... the blinking symbol of where you type... elsewhere, and then place it after " Username " again.
