I bought my first Apple Watch (a used Series 3 directly from Amazon) on 12th November and set it up with my iPhone, I'm enjoying using it so far.
One question I have; in the Activity app on my phone I can see "ghost" data for 5th, 6th and 11th November, presumably from when the Watch was on its way to me.

I've looked through each category (Steps, Heartbeat etc.) but they all start on 12th November, I can't find anywhere with data from before then. Does anyone know how to remove this data from the Activity app?
