Oof where to begin. Buttons decide when they want to work (which is almost never); if you have the patience to spastically hit buttons for 5-20 seconds you might be able to set up biometric login- but this is arbitrary as it'll just keep prompting you for a fingerprint over and over for, I'm assuming, forever; finally, if you go about it the old fashioned way and just enter your name and PW, it will absolutely never ever ever work. Just get on the mobile site, where the glitches are predictable.
