Unwanted vertical scrollbar in sidemenu template under android

I’ve just created an app based on sidemenu template.
On iOS simulator it runs fine.
When running the app in Android (built, not emulated), it shows a weird vertical scrollbar, it seems belonging to a container which is never used:

  1. when the side menu is open, the scrollbar covers the whole height
  2. when the side menu is closed, the scrollbar is partially covered by the list items.
    Could you point me in any direction please?
    Thanks in advance :slight_smile:
