Can I get a screenshot? I can't seem to reproduce what you are describing.

I attached a screenshot, but one way to repo on your end is to create a bookmark with any non-url string for the URL field (one example of this in practice would be a javascript bookmarklet).

[ios] Center Title Label if no url in TableViewUrlCell

If no metadata label is set, alignment property of horizontal stack view should be fill so that the vertical stackview can fill entire vertical space.
If URLlabel has no text, then it should be hidden so that the title label can be centered within the vertical stackview.
