I need this question answered before I go live with Ad Mediation because I want to make sure I have something to fall back on if the Waterfalls and Bidding fail me. Is having Unity Ads as the backfill option and *nothing else* enabled the same as having Unity Ads without being in the Ad Mediation beta. In other words, if I go live with Ad Mediation but the only setup I have is for a Unity Ad backfill, am I getting exactly the same results as though I had never entered Ad Mediation? I feel like answering this question and explicitly stating it as truth would help bring more people into the beta. You're asking some people (at the moment, me, for example) to test what is essentially their livelihoods against this new system without the ability to roll back. I think letting people know that they can get the original ad setup while in the new mediation system would go a long way to quell some fear.
