Thanks for letting me know about that. It’s definitely a mistake. I updated the code. You can see the final code here in case some more stuff is confusing. I don’t know how I made that mistake. Sorry about that :)
Hey, yes. I haven’t been updating the application, some stuff changed on the backend that’s still not updated on the app. I’ll have to take it down for now since I re-using the backend to build a more stable front-end desktop application at some point.
