Can you use Pig’s lab?

Hello. I am a Korean user.I want to ask you one thing."Can you use Pig's lab?"When I try a free upgrade during Pig's Lab tutorial, the application automatically shuts down.So, I can't use Pig's lab.I sent a message to Rovio Instagram to report this issue, but they don't read the message.I would like to know if this problem also occurs in countries other than Korea.How is your situation?In addition, does anyone know the developer's contact information?I really want to solve this problem and enjoy the game!
