The company has already faced threats of class-action lawsuits and loss of customers as a result of the previous outages. Customers have complained that they have lost out on some of the biggest trading days, in some cases costing them thousands of dollars.

Robinhood is going to need to demonstrate they can solve their issues once and for all if they hope to keep existing customers, let alone continue growing.
