Unable to scan Barcode; crashes when user taps 'Machine Problem' button. – Fixlaundry Review

I have installed the app on an iPhone 7, running iOS 12.1.2. When I tap the 'Scan Barcode' button in the app, the "Please enable the Camera." dialog is displayed. But when I navigate, as suggested, to Settings > Privacy > Camera to enable such usage, the 'FixLaundry' app is not in the list of apps that have requested such permission. If I enter the washing machine ID number manually, and then tap the ‘Machine Problem' button in the app, it crashes immediately. This app should be removed from the App Store.
