Ok I have figured out how to get iOS to get the bell showing.
Click on the - three lines on the bottom right. Go to settings.
In settings click on notifications. Once in the notifications settings, Make sure every notification is checked on.
Once that is done, go ahead and click the home button if you’d like or any other button to get out of the screen.
Next: you must log out of your account. After you’re logged out, re log back in and click on person logo and you should see the bell logo.
Good luck
