After the Windows 1803 update, I realized that the once useless and built-in Messaging app in WIndows now shows all my SMS text messages that I receive on my WIndows Phone (Lumia 640 XL). However, in the input box it says “read-only message”.
I have been using Cortana on desktop to send text messages directly via Windows Phone without having to type on a touch screen, and the messaging app beginning to take shape is quite exciting.
