Hi Ivano,
Thanks for your interest in
Syncfusion products.
In order to use the reminder support available in SfSchedule
control to notify the appointments(before the appointment occurs) based on
ReminderTime, you have to set the “ToastCapable
= Yes” in your project, in the “Application” tab at Package.appxmanifest file.
Please let us know, if you need
any further assistance.
Regards,
Joy Oyiess Rex K
