Hello WW1948
Sorry to hear of the Connect App issues in regards to connecting to your hub, scanning and ordering pods. We appreciate you taking the time to raise this via the forums.
Depending on the device and operating system there are some steps that can be taken. For iOS devices the Connect App will only allow one connection in regards to the settings option via the Connect App, IOS has also introduced a private address setting for Wi-Fi connections via the device. This can interfere with the app when connecting to the hub.
For Android based devices, we've generated support pages highlighting issues that can prevent the App connecting to the Hub and what to do to fix them on your device. These can be found here.
