We aren't saying "this app isn't good at trading stocks"
We're saying this company is not good at trading stocks.
The review section should be an honest forum for the app and the service the company can provide through the app. Do you really expect the common person to point out if the app made followed the fundamentals of UI/UX design? The review is to express users' experience, which can involve poor app design and/or poor service.

What? No. I expect them to say "it looked like my GME orders were submitted, but I don't see them going through", or things like that, if such problems existed. You don't need to be a UX expert to review a poor UX. But when the store asks you "is this app good at trading stocks" and you say "no it's awful, and I'm also not saying this app isn't good at trading stocks", you're not answering the question they're asking.
