i cant make shows or singles, am i missing something or is it a bug?
First of all, there's a known bug in this version that breaks the game for users in some regions, setting your date format to English might help: https://pbs.twimg.com/media/Dvv-hiBXQAE_JU5.jpg
But generally, this is how you make singles:
1. Click the play button in the bottom left. If days don't change, then it's definitely a bug.
2. Build rooms, hire staff, drag and drop them into the rooms
3. Wait until they earn enough research points. Unlock a genre, etc in the Research tab
4. In the singles tab, click the green button at the top "New Single". Enter single's title. Select genre, choreography, lyrics and marketing options. If it's not a digital single, enter number of copies
5. Drag and drop idols into formation
6. Drag and drop the single into rooms with staffers (make sure they're not busy with training idols or something else)
7. After all 4 staffers are done, click Release. If you don't have enough money to release the single, you can take a loan by clicking on your Producer and selecting "Loan"
