Repeated verification code popup when I use the app "Music" with WiFi on
I can't say with absolute certainly but the best guess would be that, so long as these requests/confirmations always appear within a few seconds/minutes of you activating the function, that it's simply not accurately logging your location.

I live in London &amp; most times these requests appear to come from an area within 5 miles of where I live.
However, when I visit my relatives in Tenerife, all requests of this type appear to originate in Madrid, some 2000km away.
I've simply got used to the idea that this always happens.
