I updated from the stable version to the Nuki iOS App 2.2.0-Beta. I was fare away from the three locks when I did this update. Everything works fine so far. Only the ring “Verbindungsstatus” does not seems to show the correct status. It is 100% gray (I am not in the bluetooth area) and after 10secs it shows green between Smartphone and Server. The ring does not show more green parts but I have a connection to my locks over the bridge (because I can lock/unlock and see the correct status on the page “Übersicht” and “Favoriten”).
