In the last few days, my Forerunner 945 has started "forgetting" my ConnectIQ watch face. I can switch to it, sometimes, and it will stay on. Then later I'll look and it'll be back to the default face. Sometimes the face I like will display the ConnectIQ "!" icon, other times it'll let me switch to it. I've tried syncing on Garmin Express, I've tried powering the watch off and back on, I've tried syncing in Garmin Connect.
Not sure what else to do.
