The app is very buggy. When I downloaded it, there was no option given to connect my machine to WiFi, and there doesn’t seem to be any where in the app where you can connect to WiFi. It won’t connect to my phone’s Bluetooth either when I select add a dispenser since it’s not connected to WiFi. There are some things that won’t open up on the app, such as users, or the contact is button, and when I put my height in, the next time I go to it, it is no longer there. This app needs a major overhaul, especially since there is no connecting the app to the machine.
