For all categories, as far as I can tell, the ‘recommended’ page is new sellers and Pros.
So, perhaps they are trying to force people to go Pro?
I mean, I don’t mind. One of the Pros in my category produces shoddy work and I have been asked no less than 8 times to rewrite their content. So, good bit of business for me.
But yeah, looks like the Pro thing was tied to the algorithm change in the first place.
