Still no fix for delayed notifications?

I'm well aware this has been posted before. It should be posted more often. This is genuinely absurd and makes these phones impossible to recommend. Almost every time I unlock the phone, multiple notifications pop up. Has anyone had success with resolving this ?

Messages seems to avoid this issue somehow. However, none of the apps that do suffer from it appear different in settings. "Manage app if unused" is off. Background limiting settings are all off. Adaptive battery off. Notifications on lock screen are allowed.

Has everyone just accepted this as a feature ? It's really my only complaint about the phone (Pixel 8, for reference), but it's such a crucial element to the phone that it is almost rendered useless.

Apologize if I've missed a recent thread that has maybe solved this. I looked through multiple threads with no luck.
