IBM Verse at ios 10.3.1

After Update to iOS 10.3.1 the Verse App never run on iPad air2 and iphone6+.

I deinstalled the App, reboot and installed on  iphone and it worked.

But on iPad there’s an error at the end of re-install.

Now it seems that the app is not complete delete (deinstalled) and want to run an update.
and that goes in to an error.
