AeroPod, PowerPod and Newton

I have a PP4..I have a road bike and a gravel bike.
I created two separate profiles in Isaac. When I switch my PP4 from my road bike to my gravel bike do I first have to connect to Isaac to “activate my new profile” to my gravel bike before switching/connecting my PP4 to the gravel bike before riding for accurate results from my gravel profile? Thank you…

If you have different speed sensors on your two bikes, all you need to do is move your PP to the bike you plan to ride today, start pedaling, then turn on PP. PP will automatically switch to the profile of the bike you're riding today.

Thanks, good information. I always thought you had to load the profile via connection to Isaac.
