Facebook app still making notification noises when notifications are off

[Android Central Question]

Hello. I have a Samsung Galaxy A8 and ever wince the new update in August all of my notifications except Facebook have been fine. My notifications are on silent and always are, and all notifications are fine but Facebook always makes a noise. I have fiddled around with every in app and phone setting. The only thing that works is putting my whole phone on do not disturb. This has only been since the update in August.
