I have problem to add new language to Storefront 3.9. I have followed this blog https://www.citrix.com/blogs/2015/09/25/adding-a-language-to-storefront-3-0/.
I use Unified Receiver UI (classic experience disabled). I have created all files by the blog artical to the new language czech(cs) but no change is visible in the receiver page in the browser. Even if I chanage the default english string bundle file nothing is changed.
What I can do wrong? Could anyne help me? Thanks
