Excepción interna 1:
Exception: Could not convert '2019-03-06,172.899994,173.570007,171.270004,172.509995,172.509995,21531700' to DateTime.

Simple line of code

var grafico = new YahooFinanceImporter()
    .ImportAsync("FB", DateTime.Now - TimeSpan.FromDays(60)).Result;

Seem it is not spliting by ","
