Yesterday I went for a run, 10k.

Usually when a save the activity on my Garmin Forerunner 255 in less than a minute I’ll be able to see it on Strava.

Yesterday the activity was normally visibile in Garmin Connect, but isn’t uploaded to Strava yet

I’ve also seen occasional late sync, but not for a long time now.  
You can still get the activity to Strava but you will need to download the .fit file from Garmin and then load it to Strava manually (use the website, not the app). 
If it continues to happen then you should refresh the settings in Garmin Connect and Strava.

Same issue started before 2 weeks. In Garmin Connect it is alright but doesn't sync in Strava automatically. Once got synced after 20 hours delay and now I need to manully upload them which is terrible. I removed the watch from Strava and connected again but still doesnt resolve the issue. Garmin 255
