Explore states "Location not available for this message"?

My partner just sent a message that I received in email form and via Explore app on my phone and Explore on my laptop,

When I tried to view the location by click "Map" tab the app said: "Location not available for this message"

When I click the link in the email message I got the map view of the earth and the message but no location information.

When I logged into the Garmin Explore site used it to view the message contents I saw the text of the message but it says "No location data available".
I verified that a location link was requested. I just added to put in the longitude latitude into the email in case she sends another message.

Any ideas why this happened?
