iOS Calendar Very Slow to Sync

iOS Calendar Very Slow to Sync

I'm using iOS 16.1.1 (the latest as of this writing) on my iPhone XMAX. I pull my work calendar into the Apple Calendar app, and everything shows up just fine. But when a change is made to my work calendar it takes forever* to show up on my iPhone. Really embarrassing when someone deletes a meeting and I show up anyway because my phone isn't updating.

*I don't know exactly how long, but it's not instant, in 5 minutes, 10 minutes, or 30 minutes. Sometimes by the next day it has updated.

In the Settings, Sync is set for "All Events" and there is no setting I can find for refresh rate. Any help on this one?

P.S. The Google Calendar app on my iPhone updates instantaneously.

It's been a week, so I thought I would bump this thread to see if anybody else has an ideas.

"...when a change is made to my work calendar..."

My work uses Google. My default calendar is a personal Gmail account, I have no problems with that.

Why does my work Google calendar not update on my phone in a timely manner when every other calendar does?

Additional Information

When I add a work calendar event on my phone, it shows up on my Mac browser work calendar right away. So things initiated from the phone get pushed to my work Gmail calendar right away, but things initiated on my Mac browser sync very very slowly to my iPhone.

iPhone Calendar? Apple Calendar? There is no such thing.

Please check which is your Default email Account for the Calendar on your device? Settings > Calendar > Default Calendar

All the devices sync with an email client server which hosts your calendar. If you have a Calendar on iCloud that will not sync with Google Calendar. Settings > Calendar > Default Calendar [Choose what you want]. What you add (Event) on iPhone Calendar is synced with default calendar unless you have chosen a specific calendar at the time of event creation.

To which email account are the calendar events synced with your iPhone? This is not clear in your post
