hello there
every week after reset i wake up, take vault items, refresh data, double check website to show new item and mythic+ key, then i go to work.
checking again in afternoon, my data is always gone.
So i guess the website resets its data way after the actual server reset time.
(i am EU)

So

Still, I upload my data after 7am, which includes my new weekly m+ key, checking after 9am, my key data is gone from the site.
