Trying to look into this benefit again and am thoroughly confused.

I have tried all sorts of searching and links but cannot find a list of restaurants that quality for the credit. Specifically, was looking for Washington DC. But I don't see any restaurants with the Sapphire logo anywhere.
Did they change how these are identified?

I linked my card on open table but still can't find any logos that indicate a qualifying restaurant.

Is anyone else having problems with this?
