hi i have same problem for some sites i get this message
https://prnt.sc/-FNzgYqeMlwZ
and opera just wont lets me to the site saying its dangerous or something. I am sure that site is legit saying that in this case its from popular video game that i want to download.
On some sites i have same message but i can just press something that allow me to go to site even when opera think its dangerous.
