Hello,
I am trying to understand how things currently work. I have created a translator for https://www.sudouest.fr that has been merged into zotero/translators master last week.
It is not currently used on French wikipedia and I have not been able to track why. I believe there might be some time needed before this newly created translator is fetched by Wikimedia server, but I could find the information.
Hello! There are few more steps for it to be used. The first is that the translators submodule has to be updated in translation-server - the last time that was done was June 25 here: https://github.com/zotero/translation-server/commit/d9e3897a6b60dc4ea7eb9e53cf5bc98b76111688
And then our version of translation-server also has to update too: the last time this was done was in March: https://gerrit.wikimedia.org/r/c/mediawiki/services/zotero/+/670809
It's a manual process, so I will try to get it updated again in translation-server (since the latest update predates your change) and then ours. Cheers!
