More than a month ago, I woke up wanting to sync my ISM device, but I discovered that it was not possible. The only solution I found was to pair it again, which allowed it to function normally the next night.
Today, the same issue occurred. As I was falling asleep, I felt the vibration of my ISM device a few times. I initially ignored it, but I can’t help but wonder if it was a sign of something amiss, such as a freeze or a similar problem.
In the morning, I was unable to sync my ISM device again and had to re-pair it.
I’m not sure what’s happening here, but it seems that after a few days, my ISM device freezes or resets and needs to be added back to Garmin Connect.
