Thumbnail Setting Disappearing

Hey, the option to set a Thumbnail disappears when creating a Token, is there any fix to this? & Currently testing things out on Goerli & it seems that the Thumbnail feature does not work either.

Can you provide a screenshot or any additional information about how to reproduce this issue? What is the file type of the token? Creators are able to set thumbnails depending on the media used for the token. If a token is an image, no thumbnail is needed. If a token is a video, then a thumbnail is used.
