I recently bought a FR 245 for my girlfriend. After the initial setup, we frequently experienced the issue, that the watch enters pairing mode (shows 6 digits) whenever the phone (Samsung A51) is out of reach for a couple of seconds.
We already tried to disconnect and unpair everything before adding the device again, but this did not help.
We also followed all of the following tips: support.garmin.com/.../
Did someone else experience a similar issue?
