This is a template for a Power App that uses SharePoint as a data source. It fills a gap in Modern calendar functionality.
Displays 3 SharePoint calendars, from 3 separate sites, in a consolidated snapshot that groups based on the calendar data is from. Uses simple metadata flag to highlight "Important" events, and call them out.
The example in this template includes the following calendars/sites:
- Company Events
- Operational Notices and Alerts
- Employee Announcements
Full details, including background, how to configure for your SharePoint tenant, and how to change data sources from mine to yours are available on my blog.
