I had to reset my watch to try fix firmware issues and when I went to install "Garmin Tides" again, it wasn't coming up in search results in the app. Finding it via Google, I see now that the FR935, and in fact, no other Forerunners are included in the Compatible Devices list. Not cool Garmin. It's one thing to not give new software features to existing devices, it's another to go and remove existing and working functionality. Hopefully this is just an oversight that can be quickly resolved.
