I cant use it unless Im connected to Wi-Fi?

I use this app all the time but a couple months ago there was an update and since then I can only use the app if Im connected to Wi-Fi. Well once I leave my house thats it I can no longer use the Messenger app. Unless I go somewhere that specifically has a Wi-Fi connection I can connect to the app is obsolete. Super lame! Im not sure if it matters but Im on an iPhone 7.
