I have had my Forerunner 935 for almost 1.5 years now. When I first this watch I was an early bird waking up at 3:45AM to go for runs before work. I have since then stopped running so early in the morning and have deleted that alarm. Randomly though during the week I will still have an alarm go off at 3:45AM. I have tracked how random this is, I once had a stint where the alarm did not go off for two weeks, but then this "ghost alarm" went off two days in a row.
I have factory reset this watch 3-4 times in hopes of resolving the issue, but with no luck. Has anyone else had this issue?
