Answer 1

Unfortunately, not all input methods are recognized properly. One workaround is to place a macro like the following somewhere in your code:

#define dummy cin >>

That should trigger the input box in place of scanf, allowing you to enter input like normal.
You can also report this via the in-app feedback tool or by mailing [e-mail] if you want, but as far as I know, it has been like this for years now, so I wouldn't expect much from it.
