On the top right corner of your page, you should see your profile picture with a little with arrow pointing downwards.
Click on that, and you should see a drop menu appear... One of the items on that list is notifications.
My notifications aren't showing up on my profile. How can I view them?
There is a bug report I put in because my notifications won't go away.. So you may be experiencing what I'm thinking is a bug, but I could be wrong ,
