Mobile App

I don't. I just use the site in a mobile browser set to request the desktop site. A better mobile experience would be great though. 

You can also open it in a browser and scroll to the bottom and select mobile view which is exactly like the app.....The app is poor but my understanding is they will be working on it in the near future and they have just enabled, or are about to, 2FA required if you have it set in your portal
