Waiting for connection in Messages

What messaging app are you using?

Have you checked to see if your messaging app is being put to sleep or deep sleep by the OS? Settings>Battery and device care>Battery>Background usage limits>Sleeping apps / Deep sleeping apps If you find your app here remove it and see if your issue improves.

Are you using a data saver, memory saver or any kind of booster apps?

Does this happen for all messages or just MMS?

Does it happen the second message if you send two in a row?
