iPhone Safari new tab is now completely blank page

Previously, when I would open a new tab in Safari, it would show me my favorite bookmarks. However, lately it shows me a completely blank black page. I have looked online about how to edit my start page in Safari, and they all say there should at least always be a button that lets me edit the page, but there is literally nothing, as my screenshot shows. I have recently migrated to a new device (from 6s to 16e) and applied software updates; it is possible that one of these events is related to this problem. Any advice?
