404 Error - Yahoo API changed? yf.download(ticker, start='2022-01-01', end='2023-11-30') works but not yf.Ticker(ticker).info ?

Describe bug

404 Client Error:

Has the API changed?

I will try rewriting my client application code to simply the way Yfinance is used to see if that fixes my responses.

Download works, but not the info() method. Here are simple test code functions and response values below.

import yfinance as yf

def test_yfinance(ticker):
    data = yf.download(ticker, start='2022-01-01', end='2023-11-30')
    print(data)

# Test the function with the AAPL ticker
test_yfinance('AAPL')
