"recommendations" empty when the ticker contains a dot
I'm trying to get some info for the AEX index. All of these stocks on Yahoo have the ".AS" suffix. However, when trying to get "recommendations" on these stocks, it always returns an empty array.
some (but not all) stocks are listed on multiple exchanges. An example would be ASML. Getting the recommendations for "ASML" works. Getting recommendations for "ASML.AS" does not.
The Yahoo finance website lists the different recommendations for both stock symbolls: https://finance.yahoo.com/quote/ASML https://finance.yahoo.com/quote/ASML.AS

It seems that the issue comes from that yfinance.utils.get_json("https://finance.yahoo.com/quote/ASMl.AS/analysis") or yfinance.utils.get_json("https://finance.yahoo.com/quote/ASMl.AS/") don't return anything for the recommendations. 'upgradeDowngradeHistory' is the name used to store the recommendations there.
What is displayed on yahoo finance web page might be sourced from the ASML data and yfinance might have to do the same if it want to support the derived tickers from the different exchanges.
