Hello,
I just received my fenix 7X Sapphire and tried to add it to Garmin Connect on Android, but right out of the box, the watch and app could not find each other. This is with Garmin Connect (latest version downloaded from the Play Store as of February 4, 2022) on a Galaxy Z Fold 2.
I figured that the watch firmware might need some updating (it was 6.x something), so I used the charge and sync cable to try to update the software via Garmin Express on PC. The watch was able to receive an update to 7.20, which I then installed. However, Garmin Connect and the watch still could not find each other.
I tried the same thing on another phone (a Pixel 6) with a fresh install of Garmin Connect and the 7.20 watch firmware, but it also had the same problem - the watch and app could not find each other.
I then tried the same thing on an iPhone (a 13 Pro Max) with a fresh install of Garmin Connect and also the same watch firmware, and it also had the same problem - the watch and app could not find each other.
The unusual thing is that on Android, if I set the watch to Pairing mode, the phone is able to see the fenix 7X and make a request to pair, and the watch responds by showing a six-digit pairing code. Pairing is successful if I enter the code on the phone, but the Garmin Connect app still can't see it. However, when I try the same thing on iOS, the iPhone's Bluetooth scan can't see the fenix 7X when it is in pairing mode.
Is anyone else having issues pairing their fenix 7X (or 7 series) to Garmin Connect? This is a very frustrating issue to have with such an expensive watch!
