-snip- It seems like their email service is a bit slow, I got the email after 2 min. So yeah you need to wait. I though this problem only for me so didn't have much thought about it. After the verification I was able to claim the 10 free spin.
In my case, hours have passed but I didn't receive the email. I tried reaching out to customer support via live chat, and they were pretty quick to respond.
-snip- My advice is to make decisions considering all aspects. Because I have faced technical issues at every step. Maybe, issue still exist, according to (TypoTonic) comment.
Seems like there are still some technical issues
(at least according to my experience). The verification email they sent me didn't work and it just redirected me to the website. Later on, they had to manually credit the free spins in my account. Hopefully they're working on fixing these problems.
I had similar issue too, verification e-mail never arrived (I tried to verify it in order to see if 10 free spin bonus works).
I encountered another issue when I tried to log in few days later. For some reason password that was saved on my browser didn't work so I had to reset password by e-mail. Fortunately I received that e-mail and had no issues after that. I am sure casino representative will pass on our feedback to developers and that these issues will be fixed soon.
