To increase the number of subscribers, you need to constantly take pictures of Anna wherever possible.
I do but after going past 30 000 it goes back to 15 000 -17 000 I had to use cheatengine
Two weeks of taking photos and there will be 30,000. Even despite the fact that after the first week the number of subscribers will fall. That's how it was for me. I took photos everywhere I could. And no cheat programs are needed.
