I contacted Wahoo service and afterwards posted the below to their contact us link. Even GPS speed does not show on the app now.

I am a new Wahoo product user, having just purchased the Cadence and Speed sensors. At the strong recommendation of one of your support people I called before i purchased these devices, I downloaded the Wahoo Fitness app. I called initially because there was so much bad feedback on the Amazon website about the products not pairing properly, and dropping out. She assured me that if i used the Wahoo app, I'd be OK.

I've spent three days trying to get the speed to display on the app without success. I did all the magic dances on the website ... forgetting sensors, re-pairing them, reloading the app, even the rub your belly and chew gum thing of putting the battery in upside down (which is ridiculous). I was sure the problem was me not using the app right, but the speed sensor was reporting speed properly when I looked at the sensor menu ... just not on the workout display.

I finally called support in defeat, expecting to hear, "Oh, you just need to turn on this button in the app", but no ... what I got was, its a known bug, and sorry about that.

It would really help if you folks could save all of us a bunch of time and pain by letting us know what bugs you know about that lead to the product not functioning. I know you get bugs which are really new feature requests, and I'm not suggesting you discuss those. But this problem ... the device is useless this way, and if you have no baseline of experience with the app, you have to assume that with Wahoo's reputation ... the problem must be that you don't know how to use the app.

In the second call in which I learned of the bug, I made this recommendation to the support person, who pushed back really hard and said no website communicates bugs. Well, that is not true -- I am an engineer in a company that makes medical devices and I can assure you, we communicate major functionality issues, and workarounds, to our customers.

So, where I stand now with Wahoo is, out of the box, it doesn't work, and the company hides behind their support team in situations where there are major functionality issues. That second call sealed up a pretty bad view of Wahoo in my mind, and it did not have to happen. All the guy had to say was, "Hey, that's a good idea, I'll pass that on." But no, he stone walled me. AND, no timeline for a fix.

Guys ... my magnet driven Catseye provides superior information, the cadence never wavers and speed always works. Those are some really basic features in a bike computer, which do not work on the product and app I purchased from you.

I no longer care about the sensors not working (people make mistakes) ... my issue now is with Wahoo's customer focus.

No response to this is requested from you.
