notification history?

I assume you are referring to smartphone notifications?

If so, scroll through the widgets on your watch and you should find it. (Up/Down from watchface) If it's not there, you will have to add Notifications to your list of enabled widgets. (Menu - Settings - Widgets - Add Widgets)

In the widget you will see previous notifications, given that you have not already read/discarded them either on the watch or phone of course. In that case you won't be able to bring them back. (at least that's how it works with iOS).

I do have notificaon widget but there is no log for eg. daily floor goal ... :/

I see. Those notifications are something different than phone notifications.

The goal notifications can’t be shown again as far as I know. But you know the different activity metrics has their own widget where you can see today’s progress?

No, I will take a look. Is there universal widget for activity metrics? 

Thank you 

I’m not sure I understand what you’re asking and whether this answers it; but there is a widget called My Day that sums up steps, floors, calories etc.

I believe it’s enabled as default, so you should find it when cycling through your widgets. If not you’ll need to add it. (Same method as in my first post).
