Like in https://gitlab.com/fdroid/fdroid-website/-/issues/643, the `hreflang` links only point to `f-droid.org/<lang>` and not to the relevant page, at least when reading news items. It got fixed for packages and pages with permalinks (should be tutorials and docs from the default value in `_config.yml` and some single pages) For every other page, this is caused by using `page.permalink` instead of `page.url` (see https://gitlab.com/fdroid/fdroid-website/-/merge_requests/1167, where I fixed it for the canonical URLs and `og:url`).
