We are both using the Message+ app on our Android phones. When I look in the Smart Family app and on the website, it does not always show up in the logs.
I know how important it is to back up important messages. I am sorry to learn of any issues, and I'm happy to help. Tell me, when did this begin? Have you synced the messages across devices, using Messages +? Do you get the same result when checking each device? To sync the messages, please click here, then scroll down to #1 in the "Syncing Messages Across Devices" section, for the steps: http://spr.ly/6601ExVxD
