Hi Vlad,
you could try the different mediations network integrations – if you just need to add the SDK and change somethin in the AndroidManifest.xml, you can do that with the AdMob plugin of Felgo with the current version already.
The integration is different for each mediation SDK, please see the link I’ve posted for further instructions.
Would be cool if you share your experience here, which mediation networks worked for you.
Cheers, Chris
