It is to me too! I would never do that normally. It's just that it was THAT bad.
It took me MONTHS to figure out how to sell a particular fund to buy another one. Somehow every time I tried to do it, it failed. I kept coming back to it over and over and different things went wrong. It was also very difficult to figure out the status of an order.
It was literally that clunky, and I've been trading for decades. I run multiple businesses, I know how these things work, but their UI was awful.
Twice I've been unsure how to move move money with their site and twice I've contacted their customer service center who was more than happy to guide me through the process.
