I have an Epix Gen 2 Pro Sapphire bought recently which has been updated to software version 15.77. Since a day or so, its Bluetooth, WiFi and GPS functions stopped working. I have gone through the steps described in the Bluetooth troubleshooting guide ("My phone will not connect to my watch" as the question), however there was no improvement. This included a device reset, removing it from Garmin Connect and the phone Bluetooth settings and trying to add it back and so on. The device can still connect to Garmin Explorer and sync that way. What are some other steps I could try to bring back the wireless and GPS functions?
