I'm not using the Pace too much but same here too.
Was this happening too on v1.3? It's related to some strings from Stratos which enable smart data on the app, I need to checj it with more time.
Do the other data sync ok, sport, steps, HR,...?...
Those strings MUST NOT be translated, that's why the app crashes. Check Post #3.
That's right, I fixed them.
I use version 4.1.006.135988111
