Published Calendar not fully syncing with Google Calendar, Outlook, macOS Calendar

Hey everyone

I've been having a frustrating issue with the Publish Calendar feature in Garmin Connect and hoping someone else has run into this or has a fix.

Here's what's going on:

  • I published my Garmin Connect calendar and grabbed the URL to subscribe to it from other calendar apps.
  • When I added it to Google Calendar, only some events showed up - not all of them. Definitely not what I expected.
  • I thought it might be a glitch, so I unpublished and republished the calendar to get a fresh URL - same result.
  • Tried subscribing from Microsoft Calendar as well - exact same problem, only partial events showing.
  • Also tested it on my native macOS Calendar app - again, same incomplete sync.
  • On top of that, when I tried connecting it to my Microsoft 365 account, I just got a generic error saying something like "try again later" - no useful info at all.

So it's not specific to one calendar app, which makes me think the issue is on Garmin's end with the ICS feed itself.

Has anyone else experienced this recently? Is there a known workaround while Garmin sorts this out?

Thanks in advance!

  • Would you be able to upload a video showing the steps you are taking to publish the calendar?
