Unable to customise notification settings for certain Apps on my iPhone.

Many apps are missing notifications options and therefore don’t receive any notifications. Nothing has worked so far. iPhone 15 Pro Max all software is updated to latest version

no notifications options are available for many apps as shown in the screenshot. The app is not listed under notifications list either.

Furthermore, the user manual shows an option for Siri to “announce notifications” while my iPhone does not have that option and it shows a note under “Siri Suggestions” “Choose which apps can suggest Shortcuts on the lock screen.” As shown in the screenshot.

too many discrepancies between Apple information and my actual experience of system settings. I need a solution, or an answer, for all these issues and specifically for Notifications. I believe Siri is a major factor in these problems but I do not want any feedback from anyone to be influenced by any one item. All comments are welcome and are appreciated.

Thank you.
