I recently attempted to create a calendar that I could share with family so they can see my free/busy time. I created a new calendar in Zoho then shared via subscribing all of my current work(Zoho) & personal(iCloud) calendars to the new Zoho calendar.

Having done this, all my Zoho calendar entries have disappeared on Zoho.com.calendar but are still visible on native calendar apps on my devices although if I add a new entry it isn't synced to my other devices. I have attached a screenshot noting there is a Zoho sync error in my calendar app.

I can no longer see my schedule or important company events/dates.

Please investigate as my calendar is vital.
