Newbie Questions

Ok, I am really new to this and while struggling through the getting the app into GooglePlaystore I have some questions regarding the layout and menus

My main question is about menu changes daily - if I edit the menus / categories I would like shown from the woocommerce fields they should just update to the app - right? Or do I literally need to create a new app every time I change the menu - i only ask because changes made in the dashboard have not been reflected in the app as of yet - or is there a way to do this?
