On another topic, I've been using the useful Navitime app to plan, over the past several months, my (current) Japan rail travel.

A useful feature I like is the detailed train itinerary, which you can see if you click on the train shown after selecting an option following a route search. During my travels today, I wanted to check the itinerary of the train I was on, only to find that this is now blocked in the free version. A pop-up appears saying the full list of stations is a premium feature.

It seems to have happened overnight, since yesterday it worked fine.

Edited to say: I miss the good old Hyperdia days!
