Disappeared Recipes

Hi. I have been playing cooking dash on my iPhones for the past 3-4 years. I just connected to a newly bought iPad and tried playing on it using the same account. However, I found most of my recipes disappeared. Eg. ‘Auto Serve’ recipe, I have about 29/3, but now, it becomes 1/3. When I try connecting back using my iPhone, my recipes are disappeared as well. Please help me with this as I have accumulated many months of hard-earned recipes in the game.
