I am playing minecarft for like 6 years and i had a survival world with cheats off and i never went into creative in the world i tried conpleting achivemnts by defeating the ender drangon (achivement : free the end ) and i also tried getting full netherite armour (achivement : cover me in debri) but the game shows i didnt complete them although i did i tried completing the achivements in diffrent worlds in survival but it still shows i havent completed it and i also play minecarft in offline and completed the achivements in offline mode but if i have to check to see weather i conpleted the achivement or not i need to be online and when i go online and check weather i completed it or not it shows i haven't completed it this problem is occuring from the last 9 months and yes i am playing this game in the latest version 1.16.10
