Unknown status message

Good morning.

I am getting a status message appear at the bottom of my iPad (that black pop up bar) with my Go solution:  "Old location received. New location requested".

It's not a problem, doesn't seem to take long to go away, but I've never seen it before - and can't find any reference to it through Google searches.
My Internet connection from the iPad is fast - it happens both on 4G and through a wireless connection. I can find no consistency as to the cause.

My solution is using CURL functions, so wasn't sure if it was related to that at all - e.g. a message from the host.

Can anybody shed some light on this please?
