Most likely you've created your tile and created it similar to: Creating Custom View Tiles
Your issue is probably related to incomplete pageType values in Make Tiles Available to Different Page Types (PageTypes property)
e.g. to add all pageTypes, you would set the key/values in definition.json to:
"pageTypes" : ["PLACE", "USER", "NEWS", "MOBILE"]

Are you using the "old" homepage with widgets or the news page as homepage?
In case of the first this is not possible...
The seconds case is handled by Johns answer...
