Push Notifications Arent Working on Galaxy S7

A

AC Question

So Ive been having this problem for a while and it hasnt started bothering me until now. Im not getting any push notifications except from messenger and SMS. Sometimes my phone will vibrate however, yet the banner wont show up. This is even the same with spotify on my lockscreen as it doesnt pop up anymore.

Over the past few days Ive tried to look at several different things in the settings. Notifications are on, my advanced notifications match the normal ones, ive tried to follow another article says that turning off battery optimization may help, yet nothing has worked.

Please help xx thanks
