hey boys, i had the same problem as you. hoppefully i've been able to reach a kind of solution to solve this problem, i think this problem is not caused by opera but by google search. After looking for a long time, i tried to change "search engine" in the opera settings and i put DUCKDUCKGO ( you can try other alternativ ) so now my opera doesnt take me to skyjem but to duckduckgo wich is almost the same as google search and better than skyjem.
