S3 Bucket Keys and CRR

Question

Has anyone been able to get S3 bucket keys to work with CRR? I tried enabling bucket keys (on both source and destination buckets) and my previously working CRR stopped working. I disabled bucket keys and CRR started working again. Documentation doesn't list any additional steps https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-key.html

Thanks!

If your replication role policy previously match by this field "kms:EncryptionContext:aws:s3:arn", you will need to update it so it's just the bucket ARN. See "Changes to note before enabling an S3 Bucket Key" on https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-key.html#bucket-key-changes - S3 Bucket Keys uses bucket ARN as encryption context, while previously KMS encryption uses object ARN. Also, you do not have to enable S3 Bucket Keys on both source and destination buckets for replication to work.
