QuickShifter easy (iQSE)

Today my app/firmware was updated before a ride. When I left my house and went on my way my quickshifter didn't work at all. Before the update it worked flawlessly and nothing has changed on the bike. The only thing it could be is the firmware update... I've emailed healtech with no response. This thing is useless now when it was awesome. It's coming off the bike and I'm going with HM quickshifter which I almost wish I would have from the get go. Fix this now and I'll keep the product, other wise it's in the trash and I'm going to post on forums how this thing failed because of a app update. I've tried to tighten the sensor, loosen the sensor, used the setup wizard, reset to defaults, nothing. The sensor is working because I can make it function just squeezing it with my fingers... the only change was this update. Really disappointing.
