Yes, you can. By default, optimized monetization flow will be used as exit link.
If you prefer to set up custom fallback monetization scheme, please choose “Custom” setting in fallback monetization menu and fill in “Exit link” with your custom fallback and optionally - “Block link” (if you need to separate visitors that didn’t perform a subscription).
Please note: conversion postbacks will not fire on fallback monetization events. You will be able to monitor fallback monetization performance in your TubeCorporate account’s dashboard only.
