Inventory getting randomly cleared

I am on a Android Moto Z^2 Play. Occasionally after closing the game and re-entering later, my inventory gets cleared, as far as I can tell there is no pattern. I am in 1.2.10, but it is also worth noting that it has happened with two different Xbox accounts and to different devises, the other was an iPod 5 on iOS 10, thank you for your time and hopefully y'all can find a solution
