This right here is why I'm so hesitant to leave Interactive Brokers in search of better commissions. "Move fast and break things" is a fine mantra for a startup, but I'm not trusting my trading account to it! This sort of development and QA failure is endemic of the attitude of RH, to say nothing of the infinite leverage debacle of last year. I don't have much faith that other fintech startups are any better when push comes to shove comes to panic.
In my mind, the commissions I pay to IB give me peace of mind that one, their platform is robust (even if TWS looks terrible) and two, when the &#@$ hits the fan, I can call an actual human broker on a telephone who will follow my instructions to safeguard my account in a crisis. Robinhood has an email address. People who were positioned short lost hundreds of thousands of dollars today because there was no way to execute trades, and RH is about to be in a(nother) mountain of trouble.
Maybe I'm tarring an entire class of companies unfairly, but I personally prefer being able to sleep at night to saving money. Call it insurance.
