If you click on it, it brings up Glympse, an app that lets people "follow" you on a map. It gave out way too much information so I did not agree to it. It showed up on a post where my daughter and I were discussing where I was and when I would get to her place ... kinda spooky if you ask me!
That makes sense, but
Go to one of your text conversations and tap the + sign. That will now bring up Postcard, Picture, Audio, Glympse, etc. Tap on Glympse and choose DECLINE. It won't show up again.
No, that should cover all of them Also, I would go to your phone settings and find "location" make sure that is OFF. There are other apps that like to track you, but as long as location is off it won't allow them to.
I routinely turn off location tracking, not just for privacy's sake but also because it can eat battery time. The only time I use it is when I'm using Google Maps real-time navigation, and the only time I use that is when I'm testing to see if it works. (So far as I can tell, it's worthless.)
Declining it means it does not install on your device. Check your app drawer, and check under ALL apps in your App manager; uninstall it if it is there. If it is not there, and you have "declined" from within your texting app, it's not installed on your device.
