Needs update

I love fb messenger but theres been so many problems with it lately. When I try to see when someone was last active first itll say 19h ago then 1 min later itll say 2h ago. Which one is it ? Also its moving very slow and keeps closing when Im on it. Last thing the pic in the persons little bubble thing doesnt always change when they change there picture. Needs a major update it was PERFECT before.
