This is useful except if you understand the language that your apple store is currently in. Unofrtunately, mine is in Japanese (after having visited Japan) so I have no clue how to follow your indications!

I have been payign a subscription for various months and have not been abel to cancel it. 

hi,

i was able to switch from japanese back to finnish by logging out from appstore in settings. then opened appstore and signing back in. it made the switch to my language automatically. maybe because my ipad knows my current location. good luck!
