Hello Hangár-One,
I am sorry for inconvenience.
We are aware of problem with translations and are are currently working on solving the issue. The problem is that we recently started to hit daily API limits for translations. We are currently negotiating to increase the limits.
Please try the translation again, most preferably few times in a few days. If it does not work at all, please share your Diagnostic Information (secure://settings/diagnosticInfo) and we will try to investigate your issue further.
