We heard from a few of you that you were running into a little trouble with the Yandex Translate component so we pushed a fix that should have solved the problem.
We also added the option for users to create and use their own Yandex API key which will give you more control over your key in case you expect your translation usage to be significant. As far as we can tell, unofficially, you should get up to 1M characters / 10M characters per mo of translation with your own key.
Please let us know if this did the trick!
