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.
If you're talking about email wofs, then you should try to change the client seed before solving the captcha, because when you solve the captcha you actually execute the wof spin.
If you're talking about premium wof (the one that has no captcha) you can not edit the client seed because opening the wof executes the wof spin.
It doesn't really matter if you click the spin button or not, once it executes you'll get the reward.
You can check your roll history, it doesn't show up immediately though.
