Query: not compatible with os mojave

It worked okay for nearly the first year I've owned it -- it was easy to use while running, it found a GPS quickly, and the battery life was decent. After I moved to a new state, it ceased locking onto GPS in my new surroundings, even with my diligent software and satellite updates. I recently updated my Macbook to OS Mojave, and now the Timex Connect app is completely useless, as it seems to be incompatible with the latest operating system. Come on, Timex! The Ironman GPS seems to have a short shelf life, making it not worth it.
