My galexy note 4 edge wont fast charge anymore. The option in the settings wont let me enable it

I want to enable my fast charging but my phone won't let me select it. Without the fast charge I can't even get it to charge. Takes three hours to get to 50% and drains in a half hour. Even an app that will allow fast charging would help

Not sure why you can't enable it. Is it greyed out or something? In order to enable fast charging, you have to change the setting before you connect the cable. If you connect the cable first, then try to enable fast charging, it won't allow you to do it.
