actually today downloaded update if paused on 80 or 90 or any % then tomorrow it will download from starting so if downloading update then complete it that day otherwise the next day it will download from starting

first of all stop auto Download....
then update in the stable connection ... and if you lost your todays data then it stopped and remember to not to clear cached data ... yes if you clear cached data... the file will be deleted ...
then 2nd thing happend some time that is ... if download form ur mobile data ... only download from mobile data... if u downloaded form the wifi then whole download should be downloaded by wifi... if u mix this it can be delete ur previously downloaded file (bcz i faced this too) ...
so make sure to download from stable network (prefer to download at night -the speed is max and stable) ...
i think its helpful for u ...
i faced too this type of things but then i done by this followed .. i can download easily without interruption... 😇
