I have a Samsung Galaxy Watch Active 2, with all apps and the watch itself with the latest updates.
Yesterday I did a bike ride of approx. 14km, with a short hike afterwards (Approx. 1,8km). When I tried to save the hike the app said "Strava needs a longer activity to upload". I discarded the activity, and started a new bike ride. This bike ride was approx. 15km. When finishing this, the app gave me the same message. Today I did a new bike ride (Approx. 5,5km). This time I used both my phone and the watch. The watch gave me the same message, needs a longer activity to upload.
Hi! Just to say that I had the same message on my Samsung Galaxy S3 Frontier. After that I didn't receive that message any more but last two days no Activity hasn't been uploaded from my watch to my Strava account although Strava on my watch says 'Sync completed'!
The same thing happened to me.....now I take a pic of my activity on watch as soon as I'm done just in case it happens again.....thwn if I can post from my watch I manually put in Strava along with photo of activity on the watch.....which sucks tbh. I hope this gets fixed
