Hi @psykro,
I am able to create multiple series but I would love to have a specific settings for the language, eg. en_US, es_ES etc..
I am saying this cause I have two series and one of it is in italian and I am thinking to add another language cause I am able to speak those languages.
I have added on Spotify my podcast and I was able to set the language but on iTunes it seems the language comes from the feed.
I think, adding a setting param of the language for each serie and also the cover would be a great tool for multi-lang based podcaster.
I hope this help, overall the plugin is very useful.
