Yoast SEO vs Smartcrawl in Upfront/spirit


It seems that the Yoast SEO plugin does not read the info form pages created in Upfront, because there is no content in the backend. Is this really so or is there something we're not doing right here?

The blog posts in Upfront however seem to have the content of posts in the backend as well and Yoast is working there as it should.

We would like to use Yoast in the pages as well, but it this really is not possible in Upfront, is there any harm in using Smartcrawl in the pages and Yoast in blog posts?

Thanks so much for your help!
