Issue with Transposing Time Series?

Questions

I’ve had a working model of a financial graph model based on the blog post:

However, since upgrading to 12.0 I’m running into an issue when trying to transpose the time series.
I’m not sure why this is happening. Can anyone else validate or advise on what has changed?

port = {"AADEX","FGCKX","WFDSX"};
portRe=FinancialData[#,"Return",{{2019,1,1},{2019,5,03}},"Value"]&/@port;
portRe=PadLeft[portRe]
portco=Correlation[Transpose[portRe]];

Thanks

FinancialData used to return list of {date, value}. In version 12 (and in 11.3) it returns a TimeSeries, so you have to extract the data before you can transpose it.

portReData = Map[#["Values"] &, portRe];
portco = Correlation[Transpose[portReData]]

Thanks.
That worked.
Most of the time everything works fine, but little changes can produce unexpected results.
