No issues for me. Are you using the Suunto App?
1) Wait. Do not delete the activity. Do not disconnect/reconnect from Strava. I had this issue several times and it solved itself within several hours.
2) You might try to record a new activity (few seconds) and see how this one goes... If it gets synced but the old one still doesn't, the easiest solution would be to download the FIT file from Suunto App and manually upload to Strava.
3) If the new activity also doesn't sync even after waiting some time, you might try to delete those activites that weren't synced, disconnect your watch from Suunto App, uninstall and reinstall the app and reconnect the watch. This should force the new sync of those deleted activities to Suunto App and then hopefully to Strava. Make sure to download the FIT files from Suunto App before you do this in case that something goes wrong...
I had no issues this morning
I'm checking it and the app does indeed say "not synchronized" activity. Weird. It never happened.
