Hi
Using the Android earthmate app, I sent messages to, let's say, He didn't get them. Instead, a few days later, Mary was sitting next to me with her in reach, turned it on, and my messages to John showed up on her device. My own in reach device's screen claimed they had been sent to John, but here was Mary receiving them.
I've been talking about this to Garmin customer support and they have been nice but their responses are like, update/refresh/resync/reboot, but I won't them to say something like, "Oh yeah, that is a bug and we fixed it", or "That's a bug and we are going to fix it", because I want the device to be dependable for me and others in the future.
