Q: Sharing iCal to friend, Link Doesn't Work

Hi community members,

I've create a calendar on my Calendar application, to be shared among my friends.

This is the link :

webcal://p16-calendars.icloud.com/published/2/M-vHE4-kKygEm5ZPcEnEtpDpIU6sQ28SR6 BPVm0Pp1VbxVoIyfoS4QdiZJe5UAlS3EyYODH7ZfpAdnTWvmQu3HUA_DNn5y7jQYtzbVDV99I

It seems like nobody had been able to click on it and subscribe to it. I am the only person who can access this link on my Mac / iPad.

I've tried emailing them the link, sending over through Slack & Facebook messenger. But nothing happens when they click on the link.

How do I solve this and share with my friends?

Follow up question, what if they are using Android / Windows, how do I share this with them?

Thank.

Regards,

Feng.
