+ **Symptom:** The Channel is `ACTIVE` but no data appears at the destination.
+ **Causes:** Service-role permission problems (delivery is retried but never succeeds, so nothing is written); no new data produced after enablement (the Channel does not backfill).
+ **Resolution:** Check Amazon CloudWatch Logs for `AccessDenied` or permission errors, and verify the service role has the required S3 and KMS permissions. Confirm producers are actively writing to the topic (check `BytesInPerSec`). Remember that only data produced after enablement is delivered.
