Can't add ICS file

Can't add ICS file

Hi there,
I am not able to add an ICS calendar event. Even though when I click on add event, it shows the event is added. However when I open the calendar it doesn't show the event. I've tried this about 10 times and it still doesn't happen.

The calendar has been refreshed, and all active calendars have been selected to show.

I've also tried to upload a local ICS file by downloading it, but can't see any options to do so.

How do you suggest I go about this.

Best,
Gaurav
