Next13 - Pages reload on route change

After upgrading our Next13 project to use the app router, routes seem to 'refresh' on route changes. The only route this does not occur is the home route.

I am attaching the development URL to see what I mean.

Thanks

Resolved.

Applied internalComponent={Link} to every PrismicLink

Once PrismicProvider is working for the app router, the need for this should be removed.
