Notifications push sur Andorid et navigateur ont cessé de fonctionner il y a environ six mois

I read through the posts here about push notifications stopping working after Google adopted a new way of handling them and that the issues seems to be resolved for Discourse. Our push notifications never came back on though and only work if a user manually enables them by clicking on the icon next to their address bar.

Have i missed something i needed to do to get them, and the fix, working?

@Falco any ideas here? What extra data do we need to debug?
