I'm
having the same problem. I get the <language>en</language>
tag when it should be pt-br (portuguese). Because of that, I'm having
trouble getting my podcast out there. People try to find it on podcast
apps and have no success, unless they turn off the language filters.
I
need to solve that problem. It should be as easy as the rest, but no.
Plus, I don't know how feedburner decided the tag should be english,
because both my google account language and my blogger language (where I
host my podcast) are portuguese.
