I am also having trouble getting Ad fills from UnityAds and IronSource. However, I had success getting Ad fills after I added Google (Ad Mob) to my SDK Network. The process is hilariously over complicated and fraught with potential errors, but the Ads seem to be filling. If you’re still not getting Ad fills, try to add more bidding Mediator networks and see if your get more results. I plan on keeping Ad Mob and maybe adding AppLovin to my final release.
