I don't know if this is due to textra's code or if you are using preexisting code, but searching for a recipient isn't efficient. For example, I have a contact whose first name is Zeynep. Not a lot of competition for names that start with Z. When I type Z, I see contacts that have no z in them at all. Ze, still no Z names. Zey, still don't see Zeynep at the top. Only when I type Zeyn does Zeynep make it to the top of the list.
