In the app store, the widget 'Calendar’ with platform support is available: Calendar
In the corresponding documentation, a lot of usefull configurations are specified.
But in reality, not all of them are possible in the widget.
For example, in the documentation, it is noted that time slots/time intervals are customizable.
But in reality, the default setting of the time slots is 2 hours, and there is no option to set a different time slot.
This isn't very useful for my customers, since they want to make appointments of 15 minutes, and a calendar view with time intervals of 15 minutes would suit them way better than a time interval of 2 hours.
Also the title (with information about the appointment) isn't always visible in the calender (especially when the time slot is small, like 15 minutes).
I already made a ticket about this, and I know that this documentation probably belongs to another widget (Calendar Widget). That widget has community support and the last update was in 2018. Therefore, I hope that it is possible to make the configurations that are specified in the documentation, match the newer widget Calendar.
