App in Ipad is not showing keyboard

Trying to enter new focus length and camera dimsions but no drop down keyboard when using Ipad air. However the app (bookmark in Chrome) works excellently in Windows 10 laptop, click on the line and type away.
But in IOS Ipad need the dropdown keyboard.

I haven’t had any other reports for this issue. Is this still happening for you? If so, could you please let me know which Telescopius version you are seeing at the very far bottom right of the page? It’s in grey, right below the copyright notice. Thanks!
