In ChMeetings, all Owners, Admins and Group Leaders are also Members. Therefore, they can switch from their administrative account view to their member view.
This can easily be done using the switcher at the top right of the screen, right next to the Search field.
To switch in the mobile app, select More in the app menu, then click the switcher at the top of the screen.
Once in the member view, the same switcher can be clicked to return to the administrative account view.
