My 66i is running v9.5. I just installed the Garmin Messenger app on my iPhone 11 Pro and I'm trying to pair it with the 66i. The 66i is in Settings/Bluetooth, but the app is perpetually "Searching for inReach devices" even though they're only about four inches away from each other. The 66i doesn't even appear in the phone's Bluetooth list. What am I doing wrong?
