Unable to Pull BRK.A Live Price

I’m running into issues pulling the live price for BRK.A (using the streaming method).

For example, when I pull these three symbols:
symbols = [‘NKE’, ‘BRK.A’, ‘BRK.B’]

The other symbols work, but I don’t get the BRK.A value.
[(‘NKE’, 122.99), (‘BRK.B’, 313.31)]

Is anyone else seeing a similar issue? Anything I should do differently?
Thanks!
