For those considering to update their K-9 app:
not recommended; the developers ruined it.
Several crashes of this new version (the old one NEVER quit), e.g.when using functions like deleting trashcans, switching between menus etc.
The multi-select checkbox appears to be gone for good, apparently they even disabled the PUSH feature.

Back to n-1, same as "WeatherPro 5.x" - 'developed to death'.
