Hi,
I want to use your plugin, but with Czech locale.
When I tried to translate it at https://translate.wordpress.org/locale/cs/default/wp-plugins/subscribe-to-category

It says
This plugin is not properly prepared for localization (View detailed logs on Slack). If you would like to translate this plugin, please contact the author.
So I am contacting you, if you could enable it to us to translate it.

Thanks!
