Trying demo but ical link won’t import

Hi I am trying to import the above link into either AIO Time.ly or WP Event and nothing happens. The ics works and I have it working funnily enough on the native AIO (but I don’t like the fact it deletes and readd everything each time).

Any thoughts on why it doesn’t work on the demo site?

Many thanks.

Sheila
