Product reviews for HrefLang plugin

I tried multiple times and not working. I get Invalid License Key Exception.

I have installed the plugin nothing is working, Its just waste of time.

Firstly I can't install correctly because I forget add to url www. But now working good. However some problem is if url doesn't exists, Page getting Child Action Request error.

We have a shop with several active languages. We know that proper use of the "HREFLANG" tag is important for SEO purposes. This plugin is fit for purpose and ResanehLab staff are ready and responsive to resolve any issues.
