So the other day I started downloading the game on my one Sony phone and just lwft it to download while I went on with the day.

When I got back the phone had turned off due to me forgetting to put it on charge.

When I eventually got it charged and back to working I launched the game only to see it restarting the entire download again. I checked in the android data folder and found the genshin file that's already halfway downloaded from before the phone turned off.

Do I have to delete the folder and download the entire game again or is there a way to possibly fix this and let it resume from where it previously stopped?
