Google calendar integration does not sync the events into my calendar.

I've spent a while combing the forum and support regarding Google calendar sync. I've set up the whole linking to my calendar but have sent the form to a colleague  and have tested it myself, when completing the form it doesn't save the event in our gmail calendars. What am I doing wrong? Or am I mislead in what this function can achieve? 

Many thanks

I cloned your form and was able to see the event in my calendar.

ex.

I tried making the integration similar to your form's integration settings.

If it still does not work, try to remove the integration and create a new one, see if that helps.

Let us know how it goes.
