All of these suggested fixes are not for an Android app which is where I am experiencing my issue.

This is now the 3rd or 4th time in the last month that I have run into an issue where the login splash screen only offer the option of connecting to the game via Facebook. The option to "Just Log In" or whatever the text is on the secondary button is completely gone. The problem has now persisted for more than 24 hours. I have rebooted as well as uninstalled/reinstalled the app to no avail.
