Big fan of using this extension for clients, makes checking simple and fixing href lang attributes quicker and easier than doing an audit in ahrefs or other 3rd parties- plus havnt found a better extension working this well to show all attributes.
Does not properly support RFC 8288 regarding web linking. HTTP headers are not detected
Everything works perfectly. Relative paths don't go through as stated in google docs.
