If you are wanting to temporarily prevent any listing updates from pushing through to the portals, you can select 'Hide Listing (do not show on web)' on the listing's Edit page. Doing this will halt any updates/changes from pushing through to the portals however this does hide the listing completely from your website.
Pausing the portals would stop the updates from feeding through to the portals however this does not prevent any changes that you make displaying on your website. These display instantly on your Zenu website as this is a live feed.
In summary, if you choose to 'Hide Listing (do not show on web)', this will temporarily hide the listing from your Zenu website. The listing will remain on the portals, but any changes that you make (such as updating photos, the description etc) will not push through until you unhide the listing and click Send Now.
