Keypath/search problem

Using Samsung tablet TS560/android however this version doesn’t seems to be useable/compatible with the navigraph v8 version.
So I use web version via Chrome. This has been working however now there is a problem with search mode .Everytime I use search function the keypath apears but only for a brief moment. Not able to enter any text. Tried other explorers Opera/MS/Firefox but same problem.
This only occurs with web Navigraph other app’s are working ok.

Any idea?
