We have added the ability to allow users to edit the function flows from templates when user disabled auto update or even when the template is set to none editable. 

this is used to allow the installed bot to modify some contents, such as whatsapp template message. So the template creator can move all the whatsapp template messages to function flow to allow user change it after install. and all other subflows can still be protected and auto updated. But if the sub flow template is not viewable, then even the user disabled the auto update feature from function flow, it will still be not viewable.
