What did you do?

Run 'pod update'

What did you expect to happen?

Parameter to still exist, no changes to occur

What happened instead?

When attempt I attempt to run my app which previously had no errors, I am now presented with build failed and the error message: "Cannot find 'AFEventParamAdRevenuePlacementId' in scope"

Please provide any other relevant information.

This issue only occurred after updating to the latest version, with no code changes in our app. Checking the AppsFlyerLib file I can no longer see '#defines' for any AFEventParamAd events.
