I've had the plugin installed for many months. I've been updating it. I've got two of my main Twitter accounts registered and both are in good standing.
They allow a single Tweet to be displayed and it never refreshes.
One star for working to a point, potential but I've giving a second star for allowing multiple Twitter account activation. That works well for me not like it seems to for others.
I'd happily try the plugin again and revise my review as I wish people would do with my plugin lol
