IndexError: list index out of range

The lines marked with an * are coming from a print() I added to see what the challenge options were. Neither of those match the if/elif block so the challenges list ends up being empty. Perhaps Google changed something again on their end ?

Also the MFA method selection seems new - previously it used to directly go to the "Check your phone..." step

Update: This may have been a transient Google thing. It's working once more.
