Unable to create best deals campaign

I’ve run “best deals” a couple times and had great results. However, when I go to create them now I get a message that says “there are no recommendations at this time”.

I’ve been getting this message since April.

Lightening deals have done nothing for me, and really want to run a “best deals again”.

Anyone have experience with this issue? I’ve reached out to seller central and they gave me some fluffy non answer.

Also, any other promotions you use to spike sales?
