Outlook Calendar not showing changes to linked Google Calendar

I was able to sync correctly my Internet Calendar disabling Cache under primary account.

Go to Account Settings->Email tab

Double click on Mail address, and disable Offline Settings, unflag option "Use Cached Exchange Mode to download email to an Outlook data file"

After Outlook client restart you'll be able to Add New Internet Calendars under Account Settings.

When you finish subscription configuration using Refresh button your new Calendar will be updated immediately.

I finally gave up and started using the "new" Outlook desktop app. The app UI is not as customizable as the "classic" but after I made my gmail account the "primary" account, all updates back and forth between my Google calendar and the new Outlook client worked without any problems.

I was able to get my Google Calendar working again. So, there were only 4 out of several hundred events from my Google calendar showing in Outlook.
I was able to get my calendar to work by deleting and recreating the 4 singular events in my Google Calendar. After I did that I deleted and resubscribed to the shared google calendar in Outlook and it magically imported all my events again. The one thing in common with these 4 events is they were annually recurring birthday reminders and they were extremely old. They didn't cause a problem up until the last month or two but doing this process fixed it for me. Let me know if anyone else can get the shared Google calendar to show up in Outlook again with this fix.

***UPDATE***

While I got the shared calendar to finally import it does NOT update new events. I deleted a few events 2 days ago and they are still showing on the shared calendar. So this feature is still broken.

Same for me. I have gone through all the steps. I even tried to add events on my phone and through Chrome on my desktop to see if that impacted which events show and which do not. No luck.

I am using the classic Outlook version. My company controls this and I cannot change it.

I had followed the instructions listed for adding a calendar previously, however when I went to remove them per the instructions provided there were no internet calendars listed to remove in the Account Settings window.

I removed the calendars, exited and restarted Outlook, then added in the calendars again via the "secret address." Some updates made in the past are now showing up but not all on one account, and no improvement at all for the other. Neither calendar is showing up in the Account Settings "Internet Calendar" tab.

I see the same things in the OWA version as the desktop app and on my phone Outlook app.
