We have been aware of the annoying issue where iPhone5 users and those using iOS6 have been repeatedly asked to enter their Apple ID and password every time they start LINE. We do apologize for the problem.
We are still trying to get to the bottom of the issue. In the mean time, you can get rid of the problem by following the steps below.
■Enter the [Stickers] menu and [Restore Sticker Purchases]
1. Start LINE and tap [More] > [Settings]
3. Tap [Purchase History]
4. Scroll to the bottom and tap [Restore Sticker Purchases]
5. Enter your Apple ID password
Once you have carried out the above steps, you should no longer be prompted to enter your Apple ID details.
However, we are aware of cases where you may be asked to enter your Apple ID details once again after starting LINE. If you are prompted to do so, please don’t panic! After entering your Apple ID once more, you will no longer need to do so in the future.
If by any chance, the problem still hasn’t been sorted out after trying the above, please try signing out and then back in with your Apple ID as follows.
■If the steps above do not fix the problem:
1. Sign out of your Apple ID
1-1. Open your iPhone [Settings] and go into [iTunes Store/App Store]
1-2. Tap your own Apple ID [Apple ID: XXXXX (Your ID) XXXXXXX]
1-3. Tap [Sign Out]
2. Start LINE without logging into your Apple ID
3. Try the steps above (Restoring Sticker Purchases from the Stickers menu)
4. Enter your Apple ID and password again
After doing this, the problem should be fixed and you should no longer be asked to enter your Apple ID.
We’re sorry if you have been affected by this problem.
Of course, we will keep working on removing bugs as well as improving our existing functions, so please continue to enjoy LINE and keep your chats fresh, fun and friendly!
