For android app, missing zoom control with mouse wheel.
Hello @Rado . Welcome to the forums + thanks for the input. 
Can you give a little more info?
- What phone/device?
- What version of Android + Collabora Office app?
- What mouse are you using?
- How are you trying to “zoom in” with the mouse wheel?
- Is nothing happening at all? Or it is acting strange?
- Are you using Writer or Calc?
- Does the same thing work correctly in other apps? (Which ones?)
