Hydration messing up Dynamic meta tags

[Jaxenormus]

I needed to get the URL parameters I used router.query.slug since my file name was [...slug].js but the page renders twice so the meta tags are undefined when I do router.query.slug[1] how do I fix this

URL Parameters are there on the second load
