Bugs need to be fixed

The game is not bad. It is nothing like the ps4 version of knack which is fine. Its a companion to the game to unlock more items. And I enjoy unlocking things for the ps4 version but the app consistently will not sign me in. It will switch to the internet and say I successfully signed in then switch back to the app and it says I need to sign in again. Also it wont let me go past chapter 3. The main screen will not scroll down. Therefore I cant unlock anymore items. I have the latest iPhone system update So Im not sure whats going on. Please fix these things!!
