Unfortunately, this doesn't seem to be a high priority or even on a list. The stupid thing about it is that no sharing buttons for Facebook, Twitter and the like work. In short, the fact that OpenGraph and Twittercards are not adopted for articles with SP Page Builder actually leaves many pages looking pretty stupid.
I have now taken the detour via the tool: “ ”TAGS Open Graph" from roosterz. The tool automatically adds the Open Graph and Twitter information after the first call of a page.
It pulls the data from a field that you can specify. For example:
Title = Title
Description = Meta Description
Image = Full article Image
Now I don't have to do anything manually and it works. Even the share buttons of SP Page Builder work again. Of course you can also enter things manually.
Hope it helps. :)
