I have a Win10 DeskTop PC and a Tablet. My Tablet is Loged into my Playstore Account. And I have no FaceBook App but I do have the FaceBook Messenger App. If I Send somebody an IM on FaceBook from my DeskTop PC and then Delete it it is goen from FaceBook Messenger. But if I open my Tablet on the Top Left Side of the Screen I See these little Tabls on the Home Screen. If I Swipe Down I See what I just Sent on my DeskTop PC. Now I know this is because I have the FaceBook Messenger App on my Tablet. But if I Delete an IM on FaceBook Messenger on my DeskTop PC is should be goen from Messenger. So how is my FaceBook Messenger App even Finding what I Sent? Or am I missing how this works? Thanks.
