On my smartphone or Google Calendar, I don't see all my appointments

In order to improve the performance of the display of the Simple CRM calendar on smartphones, Google Calendar, Outlook..., the period of appointments displayed is limited in time.
By default this limit is 30 days in the past and 90 days in the future.
If necessary, you can increase this limit to a maximum of 90 days in the past and 180 days in the future.

For that:
- connect to Simple CRM with an Administrator account
- go to the Settings tab
- change the "iCal calendar period" ->"Days before" and "Days after" fields
- click on "Save".
