@leocg unfortunately, that didn't work.

It went through the entire installation process and then went "app not installed! :)" like a piece of garbage.

So, basically, I want to revert Opera to the version just previous of this one (I have V75, if I'm understanding correctly).

the reason for this is I have been using Opera to also look at my social media on many websites because I don't like app clutter, and thanks to some updates on some of the social media sites, the mobile format on browsers updated past a certain point is not only unsightly, but entirely unusable just like they are on their sadly broken apps — the issue lies in that I cannot find a straight answer on how to actually do this, even from these forums.

All the forum posts I see basically say either "go to this website that has not been updated since 2012", or "get the previous version from Opera themselves, but I won't tell you anything more than that", and it's quite frustrating.

Can someone please help me here?
