Notifications does not work on iOS

Scenario: I want the openHAB iOS app to display a notification when an item change state.

The rule I’m running is the following:

rule "Alarm changed"
when
Item alarmTilkoblet changed
then
if (alarmTilkoblet.state == CLOSED) {
sendBroadcastNotification(“Alarm tilkoblet”)
logInfo(“rules”, “alarm tilkoblet”)
}
else {
sendBroadcastNotification(“Alarm frakoblet”)
logInfo(“rules”, “alarm frakoblet”)
}
end

I get a nice line of text in the log but no notification, not even in the webUI for openHAB cloud.

What am I missing?
