I have just tested this on my side and when I log in as a frontend user the pages this user has access to appear in the navigation. I am sending attacked a short video for your reference. Am I missing something in my steps?
Can you please let me know how the issue reproduces on your side? If possible, can you please record a video demonstrating the exact behavior and the steps you take on your side?
