After a week or so of use, some comments of what seems not to work:
- timeline: I am not sure how it works. I have the option enabled in the parameters and it did sync at first but now I am arriving at Friday and I have a 'end' after appointments of today while I still have entries for tomorrow and next week in the phone?
- misfit: i have regular error messages of 'sync failed'...
- during the night i usually put my phone and watch in flight mode. Sometimes it does not reconnect in the morning and I have to use the 'disable service' in the developer tools...

no big problems anyway
thanks again
