Well, it is easy to change language to english on the device (Ipad), but not in the App Store. Swedish is (un-understandybly) no longer supported in the Finland-Apple Store (Please make Swedish work again, pretty please)

Look at the solved answer in this discussion.

I wouldn't know if there is a time delay before it changes, I do know that there is a short delay when you change the language on the device becuse I have tried that a number of times.

Have you tried signing out of your ID in the App Store, then restart the iPad, go back to the App Store and then sign in again?

The last thing that I can thing of is to reboot the iPad which resets the system. Try that and see if you can go through the steps again and get it to work.

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

The language of the iTunes/App Stores, to the best of my knowledge, can't be changed on the user end, though that may have been true in the past. The stores are in whatever the official languages of that country are. This was also not always true in the past. It does appear to be the way Apple is going. Apparently, until recently, the Malaysian Store was in English. It is now in Malay.

If you look at the discussion that I referenced and that was just posted two days ago, it seems as though it was possible to do so then.

If it works, that's great. Hope, for the OP's sake, it does. I did notice that someone later in the thread couldn't get it to work. I'll keep an eye on it. There have been a number of English speakers of the Malay store who've been a bit unhappy. It would be nice to have a solution for them.

I translated the first part of the article and it seems as though we were not doing anything wrong and that the error was on Apple's end. Hopefully there will be a resolution to the soon. Thanks for the update.

Hi,I'm from Malaysia and right now the app store is in Malay. I tried all the solutions found over the Internet but they just don't work. It's causing me serious distress. What exactly happened to the user friendliness of IOS?

Things I tried:

1) rebooting

2) changing regional format

3) change my apple account to Singapore (I even used a singapore address)

4) login and out of app store after updating apple account to Singapore

Another way is to go to profile or anything that requires password and it will show a screen and switching over to your languages App Store.
