I was sick and tired of having notifications from the 2-factor auth program at worth not appearing or appearing and then disappearing before i could answer them. Of people calling and the phone never ringing. Of getting texts and never having the text appear, or rather some of the texts would appear on my iPhone and others would appear on my iPad.

Getting to the bottom of why my phone seemed to be possessed by the devil I did quite a few things but when it came to notifications:

(1) disable notifications from an app unless I really need them

(2) delete as many of the focus nodes I could so none of them could be engaged accidentally

(3) make notifications persistent all the time

(4) disable notification grouping

I see the harder the phone tries to filter things the more it loses notifications you want but of course, the way things work in real life, the unwanted notifications will always get through.

Don't put company software on your personal device. If you need to use these the company should provide them. Then with your work device, don't look at it outside of work hours unless you are oncall or senior enough within the business where it's a reasonable expectation.

I just disable notifications from these types of apps all together. I can open the app if I care to see what’s going on while away from my desk.
