@leocg No problem. I'm using Samsung Internet Browser, which has this feature, but I would prefer Opera for other reasons. Unfortunately, because of AMOLED screens, this is a must have function in longterm.
I couldn't check if the Hide statusbar setting is available in non Samsung devices.
I tried it again, but to no avail.
I set Location to both 'High accuracy' and 'Device only', but in both cases it did not work with Opera on more sites. When I tried the same with Brave, it worked flawlessly.
And I have granted Opera access to location services.
So there should be another thing which I have not enabled in Opera.
I have enabled 'Desktop site' to prevent some websites showing limited WAP pages and disabled Data saver.
