If you are using an embedded calendar on an Apple device and the calendar is not showing any events, this issue is probably due to default privacy settings on Apple products.
The setting causing the issue is "Website Tracking: Prevent Cross-Tracking." This is a common setting but Safari has it turned on by default. This setting prevents communication between websites, which is essential when dealing with embedded sources. This setting will need to be adjusted on a person-by-person basis.
