AdMob and Facebook Audience Network mediation

As per title I’ve setup FAN as a mediation source in AdMob added facebook adapter and FAN sdk jars to my project.
Set eCPM for AdMob to $0.01 and FAN $0.1 so FAN is the first on the list.
Installed facebook app on my phone.
No other code changes.

But I don’t see any FAN ads coming through :frowning:

Have I missed a step?

check the log and see what admob prints there

No error messages, just things like

I/Ads: Ad opening. isFragment :false

What messages should I look for?

Figured it out… I had to include FAN activity in the manifest as per documentation.
