Sms Notification

Hello. I am using plugin “WPNotif” for sms notifications for clients and vendors. In this plugin, support for the WCFM Marketplace is officially declared, but sms notifications are not received by Vendors. I am wondering what could be the problem? Perhaps in the Marketplace WCFM settings you need to configure something for SMS notifications from Vendors?
