I'm having a strange problem where the <title> element has no content for category or product pages.
Other pages work as expected.
On product pages the social graph tags (eg, og:title) do contain the correct values.
Where this gets confusing for me is the <title> element has a value if I use the Blank or Luma themes - it is only empty in my custom theme.
If I fill in SEO attribute values for a product that will show up for the <title> element for my theme, but that's not practical as there are over 8000 products to update. It works for the pre-provided themes anyway, so I feel like there is something else going on...
Has anyone else seen anything like this before?
