Push notification device changes do not show up for me unless I log out and log back in from the alarm.com server. How to reproduce: log into web server, go to notifications page, enable push notifications on device, reload notifications page (new push device not showing), go to address book (new push device not showing), log out, log back in, push device is now showing.
Have you tried refreshing the page instead of logging out and back in? There is a little refresh button at the top of the screen that will actually refresh the site. I would use that instead of the browser’s refresh button. I just tried it out and it works.
