@JethrinaBodina thank you for your support .. Even i thought to delete the game and reinstall but did not do that as it might lead to further loss of boosters n all.. waiting for the problem to resolve ..
@Flanje - i did that while shifting to X .. got all data and game except tht episode race and trophies.. now dont know what to do.. have sent an email to the candy crush helpline.. but no response
Thank u @Lola_Pop .. its Candy crush saga.. i had this Episode race available in my previous device (iPhone 7) and then changed my device to iPhone X.. now it is not available..
