Android 13 introduced a new security feature to block user apps to read notifications. I got this issue when I setup Huawei Health app for my band. Android 13 has built in solution for this limitation. Go to Settings -> Apps, open the app setting with this issue. There are 3 dots at top right corner, click it to "Allow restricted settings" If you cannot found this 3 dot menu, please remind only the app already triggered "Restricted Setting" popup will show this menu. Just use the app to request notification and get the error first.
