App is inconsistent and frustrating. No matter how many times I update, I find myself consistently having to delete and re-download even if no update is available because it won't play videos sent in messenger. When I say video I mean videos people have downloaded or sent within messenger or shot on their personal phones. It's ridiculous. I thought maybe it was my old phone, but even a new and updated phone is doing it too. I'm sick of having to do this or missing videos people send me.
