If you attempt to connect with someone on an anonymous code using the Gruveo mobile app and the other person doesn’t join the call immediately, you can still be notified if they attempt to connect to the same code within 30 minutes as long as you’ve enabled push notifications for Gruveo on your device.
It’s not even necessary for you to keep the Gruveo app open on your device to receive notifications. You can put Gruveo to background while waiting for the other party; once they connect, you’ll receive a push notification that looks roughly like the sample above. Once you tap it, the call will begin. Make sure that push notifications are enabled for Gruveo and avoid missing that Gruveo call, even if the other person is running five minutes late!
