The tweet button no longer uses my Twitter username when sharing my posts. I have Publicize turned on with my Twitter account linked, but as of today it has begun reasserting the "via @wordpressdotcome" suffix instead of my twitter username (@STraductores). I've checked other WordPress.com blogs that I know have the same setup and found the same behavior.
How do I fix it?
The blog I need help with is jugandoatraducir.wordpress.com.
