Elasticsearch Snapshot

Thanks.. Its working fine. So with below SLM policy

PUT /_slm/policy/nightly-snapshots
{
  "schedule": "0 30 1 * * ?", 
  "name": "<nightly-snap-{now/d}>", 
  "repository": "my_repository", 
  "config": { 
    "indices": ["*"] 
  },
  "retention": { 
    "expire_after": "30d", 
    "min_count": 5, 
    "max_count": 50 
  }
}

1)should I worry about deleting old snapshots peroidically? or retention policy will take care of that?
2) I tried to set expire_after to 1m and max_count to 5, when I create more than 5 snapshots, old ones are not getting deleted. Im able see that. I saw similar issue reported
Snapshot Retention Task not deleting expired snapshots. Im using 7.4.2. is it a bug?
