avast account connection : gmail : "The service is temporarily unavailable"

Installing today:

#1 Android Mobile Phone : Installed avast anti virus …then anti theft…then linked to avast!Acount through GMAIL email. All ok.
#2 Android Nexus 7 tablet : Installed avast anti virus …then anti theft…but can’t link to avast!Acount through GMAIL email…it says “The service is temporarily unavailable”. however if I enter a random email it works.

Am I limited to one device per account ?

No, it is GCM common error on Nexus 7.

Any advice as to the cause? It seems to only error for one particular gmail account (the one I want) ? And it didnt error on the android phone for the same account…

I tried deleting the sync account on the nexus and i added it again however even though my account synchronised avast won’t register the account

I notice there are two versions of avast anti theft. One within the google play store…and a different version when you download through the avast security app.

The avast security app download of anti-theft has a GCM signin (which isn’t working on lollipop)
The google app download of anti-theft has no GCM signin only facebook/avast

Is google registration for Avast Anti-Theft on Android lollipop supported?

I am getting the same issue today, seems that the server is down, I have to keep reloading the page.
