MobileAds.initialize does not init PollfishAdMobAdapter

[yarik1988]

I'm trying to implement PollFish via AdMob mediation, and I have a feeling that Adapter is not initialized, therefore it is unable to participate in mediation
Based on logs, the function

@Override
    public void initialize(@NotNull Context context,
                           @NotNull InitializationCompleteCallback initializationCompleteCallback,
                           @NotNull List<MediationConfiguration> mediationConfigurations) {

is never called
