[Plugin: WordPress SEO by Yoast] New posts not getting indexed by search engine after installing

Hi,

I decided to move from the All in one SEO plugin I have been using for years on my personal site and company sites.

I followed the installation details and have been posting articles using the new plugin.

However, new articles are not being picked up by Google (or any search engine).

With All in one my articles we’re seen and on Google within minutes, with WordPress SEO it can take up to 5 hours on my most busy site and not happen at all on my company sites.

Urgent help would be great.
