Not able to register event in Andorid App

Hi again,

I´m not being able to report events from the android app.

Everything seems to work ok, until I click “Upload”, then it takes me to the previous screen (the one where I introduce the coordinates and select the stage).

Sometimes without any message, sometimes with a notification that I´m not able to read compeltely (you can find a screenshot attached).

Is there any configuration step I’m missing? (I can report events via the web UI with the same user).
