This is highly unusual and I haven't seen the problem either, using Chrome. I notice in
@mkersyshull screenshot the web address at the top is different to ours, which might point to
@TRF_Olyy's point about it being ads from elsewhere/other cookies. We'll do some research and aim to resolve this ASAP.
EDIT: are you guys seeing the same pop up ads on other sites in the same browser, or solely on TRF?
I'm seeing various articles reporting similar, where you could get redirected to spam if you click the 'Close' link etc. As
@TRF_Olyy says above you need to clear your browser data, as well as other apps that have their own built-in browser (Facebook, Reddit etc).
