Thanks for the fix! I just set a resolution of 4, and almost every tile is now loading 400x400 size thumbnails. So that’s working fine. 👏

The only exceptions are a few posts with an original image upload of less than 800x800 but more than 400x400. These posts are loading the 200x200 size thumbnail instead of the available 400x400
