@dallasreds There are a few things you can try.
First thing; you mention logging in to your Rovio account but did you make sure that you also logged in to your Facebook account in the game?
With the apps; there have been issues in the past if you are logged in to a different Facebook account in the game than you have logged in on the actual Facebook app. even though you might have logged in on the same account try this; log out of Facebook in the game, close down the game, log out of your account in the Facebook account, start the game back up, login to your Facebook account in the game (if you get a question about giving permissions make sure to accept). after that you should be able to log back in in the Facebook app.
You can check the settings for Epic for Facebook if you go to Facebook on a computer and then go to the right side menu and Applications -> Games. In the next choose to go to “Your games” in the top menu. In that page Epic should be listed with its settings (if you click the cog).
If it still doesn’t work you can try to log out from Facebook in Epic, go to the Facebook page and remove the game from the page I wrote about above. Go back into Epic and log back into Facebook making sure to give all permissions.
