Unreliable App Performance – Supercuts Hair Salon Check-in Review

I have this app on my Android and iPad, but 3/4 of the time it doesn’t work to check in. I can only call!! Don’t need an app for that! This morning the app cannot be found in the iPad App Store for my friend to download! This is not unusual at all!!! What’s the problem??
