So this is normal situation that I will lose every time when reload the page and this is not a big deal?! This is insane.
No, you do not. The only difference is the moment when spin is executed.
If (after spin) you want to see what was the result, you may always see the spins history.
I don't see anything in my history and nothing change in my account. When I open the spin and reload the page to change the clien seed(cause it's frozen and can't change it manual) - the link expired and I don't get anything.
