Just tried to use Barclays online to pay a bill - to a new payee. Where with Barclay's online, you need to use their Pinsentry device. Used it many times before with Win7/Firefox until upgrading to Win 10 recently.
Can log in no problem to my account, but not get to the Pinsentry bit. Get a message saying no6 error. Using the latest version of Firefox. Tried Edge - same thing, but no error message, just spent ages trying to load the Pinsentry bit. And timed out.
Downloaded Chrome which worked. So Microsoft's finest isn't good enough for Barclays. ;-)
