If the answer is YES to both of the questions then the iPhone is working normally.
In point 2 above, this is part of the Attention Aware Feature of the iPhone. When the iPhone has your attention while you are looking at the screen (typing, reading websites or working with an app), then it automatically reduces the sound because it knows you are looking right at it so no need to issue loud notifications.
You can turn this feature off if you want by opening Settings ➔ Accessibility ➔ Face ID & Attention ➔ Attention Aware Feature set this to OFF.
