I'm trying to implement in my Unity Android game IronSource Mediation (LevelPlay) and before releasing the app I would like to test whether I implemented it correctly or not. At first, I just made a build with the IronSource demo scene, but when I opened App from my Android device ads didn't load at all. Also, I`m not seeing any errors which could point to the wrong implementation.
This is the Link with the demo apk and video https://drive.google.com/drive/folders/1S75jYeSrOzQOXTe02_gHW71gKYaPqxxf?usp=share_link
I built apk and expected that the demo ad will be shown but nothing happened in the demo apk.
