I am in exactly the same situation, having some 100 documents on New Pad, which I cannot access. VERY annoying. Anyone got any answers yet please?

I managed to find the developer and this is what he sent to me:
All is not lost. Keep the app installed.
I have come up with some fixes to let you run the app on iOS 11 and also get your files via iTunes file sharing.
It is being submitted to the app store and should be available in a few days, ass soon as it manages to get through review.
Hopefully this will help the situation.
It is really a bit of a bummer. I lost a bunch of data in old apps as well.
Actually, the iPad has been warning about this for the last year or so.
NewPad has not been available or maintained for years now, since iOS 6 or so.
It seemed everybody was be using Pages or Notes by now, since they are bundled and much better.
