I have an app ready to publish, that I plan on monetizing with 3rd party ad system. But, I don't have the ad system all setup yet. So, is it possible to publish with plans to monetize disabled at the start, or at least select the Roku Audience Network, with the option to change it after publish?
Yes. You would just go back into the workflow checklist & edit the 'Monetization' step, then ad the Ad Server URL at that time. It might need to go back thru the review process (some edits don't like adding new videos etc) but the channel would remain live just the previous RAF or no ads until its approved.
