Coursepress Not Functioning Correctly since Migration

We migrated our site to Managed Wordpress and since, Coursepress pro has become pretty unusable. It previously significantly slowed our site so we switched to a plan that had more resources to support what I thought was a memory issue. Now, Coursepress pro works so slowly that it is literally taking me full minutes to do things like publish a unit, delete a unit etc. It has taken me 15 minutes to publish two units. I have granted access to the site. Not sure what is going on but as it stands, Coursepress pro is unusable. Please help! Thanks!
