The test "treadmill" activity that I put into Garmin Connect about 20 minutes ago synched to Strava at approximately 12:30pm US Eastern 03 March 2024. The synchronization issue may be delayed, but it is effectively "resolved". However, the race I ran this morning did not sync to Strava. As a last resort, I manually uploaded the activity into Strava:
1. I went to the activity in Garmin Web Connect: https://connect.garmin.com/modern/activities
2. I clicked the Cog wheel ⚙ and selected Export to TCX (Export Original could also work, but I didn't test it out)
3. I went to Strava and upload activity > File https://www.strava.com/upload/select
4. After editing the activity, there's an orange button towards the bottom for saving activity.
I know how difficult and frustrating it is it to not find answers or workarounds when it comes to things that should automatically work. I hope this helps people who are trying to sync their Garmin activities to Strava.
