Cannot Send messages

[Timax58]

There seems to be a problem with the Messages app in android. It is always asking if i want to change it then when i do try the change button doesn't allow for this to happen. There is a very annoying one that always happens when somebody contacts you via fb messenger, i am always being asked to get the messenger app even though it is installed

Welcome to Android Central! Sorry, are you asking about the Android Messages app, or the Facebook Messenger app?
