Not very accessible for voiceover users.
The buttons for the tabs are unlabeled unless the button is selected. Reading order is extremely confusing for someone using voiceover. When I tried to login without using an email link, if I tried to type the name of my property in the box, the options that came up as I typed would disappear before I could actually click on them. Accessibility was not considered in the development of this app, as far as I can tell. That is too bad.
