Uber please help – Uber - Request a ride Review

This app is great to a degree, but I’m having issues finding a way to contact support and the app says I can leave my driver a tip; however, there is no button or prompt in my app to do so. There is also no menu item allowing me to contact Uber. How can I fix this as I would like to tip my driver through the app. Why is the option missing when it says that option should be there? Thank you for your help......
