My Login Bonus doesn't seem to be registering. Why is that?
You cannot receive your selected Login Bonus immediately but rather will receive it after 15:00 JST the following day.
Therefore, the login bonus that you received on that day is the item which you had selected at the previous login.
For items scheduled to be acquired at the next login, you can check this under "Next Daily Login Bonus Reward" located in: Menu > Status.
