Hi,
i believe the predictive background services are enabled in 1.0.49, and front-end components are delivered in the next release (which is imminent). however, don't forget that cloud operations may need to enable this functionality for your tenant.
also, my understanding is that there is a 'component subscription model' at work here too, meaning than an 'analytics' license may not have access to 'predictive' - because it wouldn't necessarily be purchased for all user types (the same would go for 'planning' for that matter)
regards,
H
