Android Messages - Sent message history

[Android Central Question]

Hello,
I am trying to switch messaging apps from Samsung Messages to Android Messages. I have a Samsung Galaxy S7 Edge with AT&T.
After I installed and opened Android Messages, all of the messages I have previously received were loaded, but none of the messages that I have sent (using Sumsung Messages) were there. Any ideas why?
Thanks,
Jason

Different databases? And Android Messages doesn't look as Samsung Messages' sent folder?
