I have "block cookie dialogs" and "accept all cookie's" enabled. I keep getting these dialogs on several sites. The only one I remember now is Bongino Report. I'll update this post with others as I find them.
I generally exit Opera using the button on the hamburger menu. I also clear tabs, history and data, which is clearing cookies as well. Is it supposed to do that? I don't have cookies selected in the "clear data" opt-in in settings.
Happens on both:
Pixel 4a; Android 11
Samsung Galaxy Tab S3; Android 9
