realwear HMT1 and vuforia chalk

I try application vuforia chalk on realwear-HMT1  (which is support vuforia view)

while login is in progress, there is message
"Oops! We can't generate your notification token.
Give it a minute and try again.
Still not working? Restart App and try again" 

i do restart and re-login many time it not work

So this mean vuforia chalk not support in HMT1 right?
(vuforia chalk version is 2.6.4)

it about my wearable device support i would purchase, please confirm
