Barclays stopped accepting Opera on my wife's computer today, but still accepts it on mine. We're both using Windows 10 and the latest version of Opera. All I get is a warning that "the version of Opera that you're using may not offer you the best Online Banking experience". In fact it gives me a better experience than Chrome or Edge. For example on Chrome I get an error message if I try to look at my Barclays transactions. On Edge I can't cut and paste things into a spreadsheet. There are strange errors with Barclays and it seems to be getting worse.
