Back button on mobile loses data (does't warn user they are leaving)

I have a Quick Base app that works perfectly fine... except:

On mobile (in Android app, or just Chrome app), I can fill out the data on the form, but if my finger accidentally clicks on any button to navigate away, there is no warning and I lose all the data I filled in.

Is there anyway to prevent this?
It seems like a bug to me.

Where's the "Leave site? Changes that you made may not be saved" warning?
