Several issues: 1. Cranky log in accepts fingerprint, then suddenly doesn’t. 2. Interface email options are displayed asymmetrically, so it’s hard to gauge initially where to press to just review previous emails, not to write one. 3. Writing an email usually results in a message expressing disappointment that it cannot be sent at that time, so your careful, heartfelt pieces may come to naught. Unless, of course, they get through anyway, in spite of the pop up telling you they wouldn’t. 4. You found an email from Kaiser you’d like to read again? Good luck! As often as not, it may be blocked by a notice that the message could not be accessed at this time. 5. You discovered a typo you would like to correct before sending your message? Good luck being able to see what it is you are changing, as, once you tap where want to write, the screen moves instantly up, and out of sight. At which point, you will need to order a sedative.
