Hi, I have a similar issue here. I am on the Suunto Run and did a 10h trekking activity. The diary on the watch is showing no activity, however the activity is saved on the watch with regular info (graphs, etc). The issue is even though the watch is syncing properly, the activity is not showing on the app… I did try everything wirelessly (disconnect, restart, uninstall the app, unpairing) but none of these seems to work.
Finally I did try to save another activity which I deleted after and it sync like it usually does.
What can be done here ? Is there a manual way to retrieve the activity ?
