The compass arrow should appear on all smartphones

This is not the case in Cartes.

By @hayriokcu.

Yes it should ! We even have a compass page that is the best hit on Google search. https://cartes.app/boussole

It's designed to work for iPhones, but it may be bugged now. Hence this issue. I don't have an iPhone at hand right now.

   I confirm that the addition to Cartes.app the compass in the https://cartes.app/boussole page does not work. iPhone 11 Safari , and Vivaldi browsers.

   You're right ! Just checked too. Some websites seem to work through a user permission.

   Got it : on iOS, user permission must be requested after a user click. https://caniuse.com/?search=DeviceOrientationEvent

   This method requires transient activation, meaning that it must be triggered by a UI event such as a button click.

   Perfect, that's it!

   Partially fixed by 1927 : @hayriokcu can you check that cartes.app/boussole works (in 5 minutes of deployment) ?

   Then we need to fix :

   • make the compass work through a user permission dialog triggered by MapCompassArrow.tsx that will be displayed on the map once (we hope it is remembered...)

   It could clash with the indoor map dialog. Make first the user answers this question first. Could need some code migration, not trivial.

   The issue solved on https://cartes.app/boussole. Now after accepting request it precisely responds to the rotation.

   However in the Cartes.app IOS mobile still do not have request so the issue persists.

   You mean the PWA ? Or the main map expérience ?
