ZML having different readings

Hello,

I’m using a kickr and wahoo cadence sensor hooked up to a MacBook Pro via Bluetooth. I run the mobile link app on my iPhone 8 as well. I’ve noticed that the numbers on the app aren’t lining up with the ones on the computer screen. Especially the wattage. Almost as if the phone is making its own readings compared to the computer. Cadence seems only off with a slight delay but the numbers at least match up. Any ideas?

Also, does BLE need to be on under settings > sensors on the app if I’m using my computer’s Bluetooth for pairing sensors?
