charge 2 walk with phone

[SunsetRunner]

Recently, if I set my Fitbit to walk & also have my phone with me (with a GPS), I get a message on my Fitbit says to press the button to dismiss the Fitbit app. It keeps popping up until I press the button. I also noticed it no longer shows the map of where I walked, even though it should pick it up with the GPS. Wondering why it tells me to dismiss the Fitbit app.

Is this message popup on the Charge 4 or on the Fitbit app on the phone @SunsetRunner

I have a Charge 2, and it pops up on that -- right on my Fitbit.
