FWIW, there have been many, many requests to Wahoo to allow for users to change the auto pause threshold via the companion app. There's a thread or two on the Wahoo Elemnt User's Forum about it but I don't think that Wahoo actively reads the forum or responds since they haven't made that change. Sometimes I wonder why the forum is there.
