If you have a Crowdfundly organization then as an organization owner/team, you can enable/disable similar campaigns on the single campaign page.
First, you have to log-in to the Crowdfundly Account. From the Dashboard, you will see the “Settings” menu from the sidebar. After going to the setting page, you have to choose “Crowdfunding”. In that section, you can see a switch called “Show Similar Campaign”. To make the similar campaign section visible, enable the switch. You can leave it disabled if you don’t want to display this section publicly.
Finally, make sure to save your changes when you are done.
