Is there anything after "I need to follow Ayane to the local fox shrine"? I beat the last boss and went to the beach. There was a cut scene and I ended up in the fox shrine, but the dress collection didn't unlock.

Since I'm adding new dresses, the updated version will be available after addon's content. Just like it was in the "vanilla" Yorna. In other words, it will be available after you'll clear the new ending.
Players who unlocked it earlier will have access to the old version of the dress collection scene and it will update with the last content pack for the addon.
