Hello Thomas,
Thank you.
The German translation is not completely up to date:
https://translate.wordpress.org/locale/de/default/wp-plugins/gwolle-gb/
I see many strings are waiting, it’s just that there is no active Editor. Would you want to become editor? That way you can validate translations and bring it to 100% translated.
Alternatively, you could work with the German translation team to get it to 100% again.
There are no automatic updates. I sometimes do send an email notification for a manual update.
Regards, Marcel
