I can’t find the answer myself. I think it should be in the store, but I don’t see it there. No news about this either - at least I can’t find them, neither in the app nor on the site.
My guess is, it’s until Oct 31 18:00 UTC.
But I don’t know if I’m right. Anyone?
There was a sale on early Oct, but it had ended already (mid Oct).
Usually, sale only last for 2 or 3 weeks.
It seems the app had cached news tiles or something. Now I see there’s no discount anymore. What a shitty way to do things. No indication when a sale begins, no clue when it will end. Can’t plan anything this way. Great.
