Okay, I published App Cloner 1.3.0 with:
• Facebook Messenger cloning
• Automation support for Tasker tasks
• Intro screens and user interface updates
Facebook cloning on Android 4.4 generally works but when you login the first time you’ll get an error message. Exit Messenger and open it again. You should now be logged in and it will continue with the registration process. On Android 5.0+ I’ve not had any problems.
