@danielzr I guess Opera simply can't do that. Anyway, try checking Android settings and see if you can allow Opera Mini to play media on the background.
@waiter Same, except I get a pop up menu where I can choose Login in with Opera, then I see a blank screen. That was on a a pretty old 3.5" Fly model with Android 4.4.2, so I thought that was the reason.
the reason I am asking for help is because I wrote my bitcoin seed in the url and save as bookmark. the bitcoin is not that big but seeing the price lately hurt me inside 😞
