I broke my wife's Windows Phone so I am passing my Lumia 1020 with Windows 8.1 to her (and using one of the spare Android devices around here)...

I am trying to setup her email account (Google Apps) but it seems it goes into a loop

 

1. create account
2. enter credentials 
3. complete first sync and emails show up in Inbox
4. get a notice it needs some authorisation
5. perform authorisation
6. return to Inbox
7. Start sync
8. go to 4

Anyone else seeing this?
