Thanks for the reply. Regarding the timeline, do you mean the logs available in 'developer tools' ? I have opened it but is not meaningful to me . Anyway I have attached a shorter version (because tmo is restricting the size) so I have kept only what has happened today and the last line of other 'generation'... let me know if you need something else.
Regarding Misfit, I have tried to uninstall it and reinstall it (to make sure I have latest version because i am not sure how to check the version of the app I have) but it is still failing at sync, it reports 'Sync initiated - Wifi required' and then 2s later 'Sync failed - network error'. If I go to settings of the app, I can see that 'your pebble is connected to Misfit account successfully [...]' and all i can do is close or switch account.
