If you have more than one property feed integrated with your ActivePipe account, within the Define Properties options you will see a Feeds sub menu.
If you only have one connected property feed this sub menu will be hidden.
Starting with an active auto-fed property panel, select Define Properties and then select the Feeds sub menu.
Here you can choose the source of the property data for this panel, using the tick boxes to select or de-select the feeds.
If all feeds are left unticked, the panel will use the default feed settings for your account (often all feeds), which can be found within your Admin account Settings menu, within the Properties sub menu.
