Hello -
Every time I change my max heart rate on my Garmin 245 Music, it switches back to the default age-based setting. I checked while it was plugged in to make sure Garmin Connect was also displaying my updated max heart rate, but as soon as I unplugged my watch, the watch settings had reverted back again. (Interestingly, this does not happen with the sport heart rate. I put in my own max in for running too, and that one held.)
Also, it does not seem like the max is auto-adjusting to a new max when my heart rate surpasses the default. I wouldn't be manually adjusting it if it had. (And I do have the auto-detect max heart rate on.)
Hoping someone can help me.... very new to heart rate data.
Thank you!
