Up to now I went through following steps:
1. I created Page. I selected template for it: blog. Saved.
2. I set hompege settings to: static page and selected page created in step above as the one that should be used.
At this stage meta formating at hompage was as I wanted it to be. (first image)
3. Then I went to Theme Options -> Layout, and set it to full-width. Saved.
And meta formating on a home page created before changed to second image.
If nothing else will work I will switch themes but I have to admit I really like Pinboard 🙁
