As an alternative to admob, which is a company that many users do not have an account with or have restrictions in their country, which is my case.
They could add Facebook Audience Netwrok which pays much better.
I would like feedback from the team, it is a resource that I have been requesting via chat for years on the mobiroller.
Taking into account that the apps are made in reactnative which is from facebook, it would be interesting to pay attention to the performance of the audience which is a good alternative to admob as it was for you to make an app in reactnative a facebook solution.
It is interesting to note that the implementation is “simple” the methods are very similar to that of admob changing only a few small details.
