You can give feedback directly within the app by going to the backstage view (the view you see when you first open the app that lets you open a file or create a new one), tapping your username at the top right, and selecting Settings. Once you're in the settings window, scroll down towards the bottom and select Send Feedback.
or another option is to ask for help in dedicated forums here.
