Missing “link rel alternate” in Web Stories

This is what I see on the Portugese page:

<link rel="alternate" type="application/rss+xml" title="Feed para Select Game ?" >
<link rel="alternate" type="application/rss+xml" title="Feed de Select Game ? Stories" >

and on the English page:

<link rel="alternate" type="application/rss+xml" title="Select Game ? Feed" >
<link rel="alternate" type="application/rss+xml" title="Select Game ? Stories Feed" >

Both look good to me.
Note that Polylang doesn’t add these links, but indeed filters the feed links just to add the language code.

Yes, but its shows from a web stories listing pages, not the rel from specific webstories.

For this example (from a normal post) shows this in rel alternates:

https://selectgame.gamehall.com.br/depois-de-zeus-hades-ganha-teaser-em-fortnite-capitulo-5-temporada-2/

<link rel="alternate"  hreflang="en" />
<link rel="alternate"  hreflang="pt" />

Sorry, your first request was unclear.

hreflang don’t appear because your post has no known translation.

I quickly tested your plugin. The issue is that it comes with a new editor (neither the WordPress classic editor or WordPress block editor) and this editor doesn’t support the metaboxes added by other plugins like Polylang. Without this metabox, it’s impossible for Polylang to save translation groups.

Hi! About the know translation for my first example (from Blackpink posts example) i configure this a few weeks ago, in web story section:

For the support for metaboxes, i can try again to create another thread for this, but the devs previously commented that the plugin had support for language plugins.

Now I don’t have much idea what to do. My fear is that Google will consider the posts as duplicates, and not have a translated version, as they are on other portals.
