Hi @doug, it says in the description that this plugin is a work in progress. You report the things that are already described in Known Issues. Yes, this plugin does as it is advertized. One can still enter multilingual SEO data needed, sometimes using raw multilingual fields – it maybe inconvenient, but for some people it is all they need. Content Analysis does not work, which is also “as advertized”.
If you wish to help, please, find a programmer to finish this development. I will be glad to help as much as I can. Thank you.
