FindMy only finds iPhone when unlocked
On https://www.icloud.com/find/ my iPhone only shows up when I unlock it!
My settings are as follows
Find my -> Find My iPhone -> Find My iPhone ON
Find my -> Find My iPhone -> Find My network ON
Find my -> Find My iPhone -> Send Last Location ON
Privacy & Security -> Location Services -> Find My -> While Using the App (highest possible privilege)
Privacy & Security -> Location Services -> Find My -> Precise Location ON
What is not working
It is not showing on https://www.icloud.com/find/ when it is locked.
It is also not showing the last position.
It basically just shows nothing, so you can not even tell where its last position was!
My iPhone is online, and it has high speed internet.
When I unlock it, it shows up very quickly in the find service.
I do use a VPN. But even if this interferes, it would not explain why it shows up after being unlocked and why there is no last position.
iPhone 13 Pro Max, iOS 18
