There are many old/partial/... threads about this where I find none of them satisfactory and sufficient.
I want to turn all notifications off of my Android Facebook app.
It has not been possible before, so I did not have the app.
I will uninstall the app if there is no solution for the task.
I have browsed all Facebook settings but they do not have anything about turning all notifications off.
I would like to find also System specific block for Facebook App i.e. do not allow it it to show me any notifications.
It would be great if you can do this without third party appplications.
