As far as I know, only during.
> I am wondering what changed though, since this hasn't happened before in the previous 4 years. More spoofing installations maybe? Higher radio transmitter power?
No clue about changes. All I can say is I never saw it when I was here last, mid-2022 for about nine months.
> I'm also very curious, do you have any technical mitigations for this to be able to use your GPS devices? Or is it now just a fact of life?
Technical mitigations? read the road signs and figure out where you are :-)
I did read about someone having trouble with scooter apps, where the app was very confused to find the scooter now in Lima.
> Sorry for what you are going through.
Thank you.
The GPS jamming is probably to confuse the missiles or drones, not the people!
