Disable activity notification

Is it possible to disable only the activity notification in the iPad app?

That feature seems to be completely broken for Japanese for me, sometimes I get five “activity changed” notifications at the same time or one “activity decreased” and 20 seconds later “activity increased” which is just plain stupid.

I don’t have that effect in other languages and in general I’m not interested in these notifications and would like to get rid of them completely. But I don’t want to get rid of other notifications like for the streak.

At the moment, the best you can do is to disable the “Streak and milestones” popups under Settings > Lesson Settings.
