Epix Pro - Training Readiness/Staus - 3 days?

I've got the Pro and it tells me to wear my watch for 3 days to give me a Status and Readiness Score. 

I had the Non Pro and I'm sure it didn't need me to do that? I never ever slept with it on and it gave me  that data anyway.

I have the Vivosmart 5 which I use for sleep, HRV and Body Battery (used to do that with the Non Pro). 

Is this one of the gaps in the Unified Training Status or do I need to turn it on somehow?
