Unfortunately that's been a too-common complaint about Wahoo for years. Products with good potential, but inconsistent or indifferent customer support.

I'm not heavily invested in Wahoo doodads, so it's only a minor annoyance when I have to repeat the song and dance every time to pair the sensors and app. I got the Tickr new, which was pricey, but paid only $10-$15 for their 2012 era iPhone speed/cadence sensor kit. It does what I want for home trainer use, but I wouldn't take it on the road. There are lighter, smaller and more efficient devices than phones that pair with the same sensors.
