Google calendar sync with Suite CRM calendar

I done ical integration of google calendar with suitecrm calendar in version 7.3 using the guide in below link.

SuiteCRM calendar syn with google calendar is working.
But google calendar didn’t sync with suiteCRM calendar.

So kindly please give the solution.

I use suite 7.2, but I would be very interested in this, too…I’m looking for a commercial connector advice / suggestions, too…I saw a comparison few months ago between different commercial connectors for sugar but couldn’t find it at the moment…

I remember there was a one-time payment add-on connector that got a nice review…I’ll search it and then post it here, but it would be nice to get reccomendations / real usage experience from real users :wink:
