if it is of any help, i have been using a OP6 running /e/os for over a year now, as a daily driver. central europe, have not ran into any issues banking wise, other than one 2fa app complaining every time it is launched (but still functioning fine) edit: sadly the battery life is now starting to decay quickly, and i also had an accident that left both front and back glass shattered, so i may soon upgrade.
tbf it seems to be a common issue with search engines atm. brave also has the stupid ai response topmost, and startpage without adblock pushes in so many sponsored results that you need to scroll to get to anything else
