Find My not working for any device - "Location not found"

Hello,

Find My isn't working for any device I have. I can see them on the list, I can make them play a sound and such. But I cannot see on the map, it says "Location not found".

I'm experiencing this for my MacBook Air, iPhone, AirPods Pro and even AirTag.

I have tried to verify and re-enable every setting related to Find My, including my iOS account.

Everything seems to be enabled.

Any guess what could be wrong?
