I bought the brand new Forerunner 245 Music last week but I've had issues since today.
The Garmin Connect app has had issues recording indoor rowing distance since last week - you can't select any distance properly, it only goes up to meters.
However, today I discovered major issues with my Forerunner 245.
Yesterday, I did a 30min indoor bike ride and it gave me a calorie reading of approx 300 and a training effect.
Today, I did the same 30min indoor bike ride, and it gave me a calorie reading of only 137 calories! It also didn't give me any training effect.
I then noticed that my elliptical session before the bike ride also only had approx half the calories burnt as a similar session 2 days ago, and no training effect. I restarted the watch, yet then went on the elliptical for 5mins as a test and it gave me ZERO calories for 5mins, which evidently suggests something isn't working.
Software on the watch is v 2.70 - anyone got any idea what the heck is going on here?
