Superstar Mode glitched for months.

Everytime I try and switch characters in Superstar Mode, the thing says “There was an error retrieving the data. Please try again later.” It’s been going on for months, and still hasn’t been fixed, haven’t seen anything on how to fix it online. Why hasn’t this been fixed? This glitch going on for months is unacceptable bro. The main feature of the **bleep** game and it’s glitched. Please fix this glitch bro. Waste of money bro.
