sharing events on shared calendars from the calendar

[fabulousmiriam]

I use Google Calendar, synced to the calendar on the tablet. I frequently need to invite others to participate, which is not a problem in the web interface - but since it is a shared calendar, when I invite someone through the Calendar app, they don't ever get the notification. I've had this problem on other devices too so I'm thinking it's a problem on Google's end - help?
