Clash of clans after official 10.3

Hey guys I just have a doubt, I haven't yet upgraded to the official os 10.3 yet even though its available to download, as I'm a bit hesitant and worried about the app clash of clans, I don't my save progress to dissappear after I do the official upgrade
So I just wanted to know if anybody who has done the official upgrade to os 10.3 and their coc village progress is fine.
Running on leak os 10.3.1.1151 Z3

Nothing will happen to your COC.

But if want to make sure, just make a full backup using Link before updating.
