Just saw this thunder sorry.
I don't use the app but have it and looking at it it looks like from the top right hit the 3 lines then hit settings and put it in signature .
Other then that I have no clue . This might not even be the app you speak of.
Thought I'd bump this so many don't put there Location in.
Please put you location in so we know where you are makes it easier to help if you need help but also its just nice to know about where you are in the world
