I love this game. I have issues with level 2 of fleet battles, I have completed level 1 normal and hard but not level 2 normal. If the last battle was on hard level, there is a lock in the place of level 2 tab regardless whether I selected normal or hard. On normal, I can select the lock and it opens level 2 normal. ON hard, if I select the lock level 2, it tells me to complete normal to unlock hard. Can you please fix the tab display to change the tab icon from lock to the level number. Sometimes I have seen this in other battle windows.
Didn't you just tell that Level 2 hard remains locked until you've completed Level 2 normal? And If I got you correctly, you have not still need to that. So seems to be working as intended.
Here is my progress on level 2
From that picture, it looks like you still need to complete 2G. Once you do that it should open the next tier.
