We're working on releasing instant sync'ing cross tenant but don't yet have a timeline.

So... "We're working on releasing instant sync'ing cross tenant but don't yet have a timeline." was the reply back in 2017. We're now writing 2021. Could it really be that they're still working on it? At least it seems to me that I'm experiencing exactly this problem still.

Torben Kirk Wolf Is this still an issue? It seems so, as I am subscribed to an external calendar from Jobber (an online scheduling/CRM platform), and the events are not updated in my calendar until at LEAST 6 hours later, if ever. Microsoft Outlook didn't seem to think this was a problem when I called... Please help us solve this issue! I cannot find anywhere to update the sync/refresh rate either.

  Yes, unfortunately, I am still struggling with this. Just today I've accepted two meeting invites that still don't show in my Google calendar 😞
