Yes, but I think it's important to note that every other broker I've used presents the information in the same way and the way they are displaying the info is an accurate representation of the state of the account at that moment.
Blaming bad UI is the easy way out here. Robinhood should take the blame for this, but not because of bad UI. Robinhood should be at fault because the knowingly allow tons of "investors" to have options trading access with little or no screening and verification.
Blaming the UI here would be like blaming a single specific gun maker for a mass shooting, when the real question you should be asking is how did this person get a gun at all?
