On my Android tablet, the Sign-in window still does not even appear.
I get just a blank white space under the green sign-in banner.
Tap to open the Survey123 app.
Click on the "Sign in" button.
In Settings, added our ArcGIS Online URL.
Click the orange button to sign-in with my enterprise account.
Next window is presented and is blank - no UN/PW entry slots.

Signing into the Survey123 app on my Lumia 950 with Windows 10 mobile does work, albeit, slowly and with frequent crashes.
I do not have an iOS device to test with.
I am able to sign into my enterprise account in "Survey123 Connect for ArcGIS" on a Windows 10 v1607 computer.
