Settings are not saved when you exit the game. But there is one setting item that is not thrown at the next entry into the application. This is the choice of file storage. Also, it is not always possible to log into a Microsoft account (Screenshot_2021-08-07-00-58-14-490_com.mojang.minecraftpe.jpg). When you clear the cache and application data, or when you reinstall it, you can log into your Microsoft account the first time you enter the game. But even at the first start, worlds from external storage are not available. It is also impossible to create a world in external storage, it gives an error (Screenshot_2021-08-07-01-23-40-872_com.mojang.minecraftpe.jpg).
