The viewneo Signage Stick and the Player App automatically update the content every 15 minutes to play the newest playlist. However, a stable internet connection is required.
This 15 minute interval is the current default setting. However, you are not limited to the default setting. You can also set an individual update interval by yourself. You can change the interval setting for either the device group or for a single device. Therefore just open "advanced settings" in your device (group) settings in your viewneo account. Alternatively, you can also change the time interval under the "update interval" setting.
