Ads Not Getting Fetched In Heyzap Mediation In Applovin.

So I saw this video of HeyZap mediation with Applovin and did everything as shown. But during testing I ain't getting even one video ad. Also, the number of Banner ads shown in also only once, After that, NO ADS.
Also in the first test screen, it shows(sometimes) in Applovin that Network Not Enabled and doesnt show any ads.
What is the problem here?

 

having same issue, logs said heyzap cant grab ad

 

forget about heyzap, better use other mediation

 

what do you recommend? that appodeal tutorial didnt work for me =/

 

@Appossible

 

I recommend admob, or some other mediation from China

 

hmmmm will try that, what have you tried from china?
