Apple now sends the Device Token in base64 encoded format for this we have to use the base64 function with the device token
instead of message.token('CgeMZKRl2cqZAmGQ0VNCvySXAsaMPqeHga9ZUC3kqpM=')
I used
message.tokenBase64("6CORK2VBuJCPi1Y8oB3PRyoIiSf7Aq5sD7noZ/Awxao=")
and this did the trick ....
