How can I use the predefined or user-defined time periods for filtering?
Apply predefined time periods to the overview
With a click on the time filters you can adjust the display period. By default, the filter "1 month" is activated, the active time filter should then be highlighted in green.

Apply custom period to the overview
If you would like a custom time period to filter the notices, then simply click on "Other time period".

Afterwards, a dialog opens in which you can enter your user-defined period.

Confirm your desired time period with "Ok", after that you should only see notes that match the desired time period.
