I hate the verification process, the SMS verification code works 1 in 5 times. I didn't have to use support yet but from what I read it's atrocious.

you can use xapo android aplication https://play.google.com/store/apps/developer?id=Xapo&hl=in
im use xapo wallet too, the sms code sometimes not work, but the 2fa from xapo app work perfectly

Plus, if we use the mobile app, we don't need to "verify this device" every once in a while just to check our balance..

Their support SUCKS big time!!! Sent 2 inquiries already and still waiting for an answer for two+ weeks ... doesn't look promising,

Uhh... their support was here just a little while ago, but now maybe s/he is gone (again).
