I bought a Wahoo Rival after Christmas, and have been using it ever since. Occasionally, the UI of the Rival locks up and I need to reboot it manually. Since one such reboot about a week ago, it lost the connection to the app on my iPhone. It also no longer counts steps and tracks my sleep.
I have reset the watch and paired again with the Wahoo app twice, to no avail. Despite the resets, steps are no longer counted and sleep is no longer tracked. Is there anything else I can do?
