Google Ads Destination Creation Fails with "UNIMPLEMENTED: GRPC target method can't be resolved" in Paid Media Manager 25

Hi Team,

I am trying to configure a Google Ads destination in Paid Media Manager (PMM) on Pega CDH 25. The Google Ads authorization completes successfully, but the destination fails to save with the following error:

Exception occurred while saving destination.
com.pega.mkt.google.api.gax.rpc.UnimplementedException:
com.pega.mkt.io.grpc.StatusRuntimeException:
UNIMPLEMENTED: GRPC target method can't be resolved.

PMM displays:

Read and write access authorization on Google Ads was successful.

However, clicking Save results in:

UNIMPLEMENTED: GRPC target method can't be resolved.

Is there a known compatibility issue, required hotfix, or Google Ads API version dependency that could cause PMM to invoke an unsupported gRPC method during destination validation?

Any guidance would be appreciated.

Thank you.
