Custom token Thumbnails + Images aren't loading!

Attaching a couple images here. I believe I’ve filled out the CSV correctly and allowed link sharing with G drive, so unsure why the tokens aren’t coming up. Have done the transaction and now all the tokens are blank with the names. Thanks in advance!

If the images aren’t showing it means the upload failed. Can you make sure the files are accessible via google drive (permissions are correct) and try the upload again?
