Very odd, yesterday after commuting home, synchronisation with Strava suddenly hung. I had to cancel synchronisation in order to continue.
Synchronisation with MapMyFitness (which happens before Strava) worked okay.
Nothing I did would allow synchronisation to work. I eventually decided to delete yesterdays activity.
After commuting in this morning, I have the same problem - watch hangs while synchronising with Strava, but MapMyFitness was okay.
As far as I can tell, Strava have no general upload problems.
Can anyone suggest what might have suddenly changed - watch has been synchronising perfectly well for a very long time.
Anyone else having a similar issue?
