I've encountered the glitch on my Android device where the restaurant is by default, Level 1. Basically a brand new start.
I sent an email to support almost 2 months ago and yet I still have not received any reply or patch. I have already tried to reinstall the game but I still can't get access to my own restaurant.

Pretty irritated at the long wait, last time I emailed support in regards to Bakery Story they were much quicker.
