Hello and happy new year my friends!
I'm trying to sync my keyboard but everytime I get the "could not sign in" message!
It's been two days now.. Is the server down or something?
Cheers

does it work now?
No still nothing.... 
Do you have an antivirus or taskiller?
No nothing! I tried to turn off sync on my Tablet Z and then back on again, it does the same thing! I also saw that the last time it synced was the 15th of December... so it must be down since then! Is anybody from Sony reading those messages? 
Same problem here: I used to have a Z3 Compact, a Z Ultra, a Z2 Tablet and a Z3 Tablet Compact all of them with keyboard on cloud sync working...
Yesterday I logged out the keyoboard of the Z3 Compact and since then no way to log in again...
So (stupid) I logged out all other devices and now I can't manage to login none of them anymore 😞

If they don't give a solution fast enough I'll go to the stock Android keyboard!
OMG the Google keyboard is awesome!! I underestimated it!! 
I get a message "could not sign in" when trying to enable backup and sync of xperia keyboard.
