URL https://api.polygon.io/v3/reference/splits?execution_date=2019-06-05&apiKey={...}

Result I am getting result for STRR ticker:

{
  "execution_date": "2019-06-05",
  "split_from": 10,
  "split_to": 1,
  "ticker": "STRR"
}

Expected Result The STRR ticker is not a valid ticker at the given date, back then the same company was trading under DRAD ticker. I would expect the reference endpoint to return point-in-time data:

{
  "execution_date": "2019-06-05",
  "split_from": 10,
  "split_to": 1,
  "ticker": "DRAD"
}

Additional context The ticker events endpoint indicated that the ticker for the company changed on 2021-01-04.

Thanks for raising this issue. We're discussing internally how to rectify this now.

Apologies for the confusion.
