I get short 2-3 seconds where it all of sudden resistance changes to 0 for a second.. then a sec later it come back harder than whatever power it is suppose to be at. This goes not occur with the Android version of the workout player. These little bumps are very annoying and power robbing to the point where I won't use the Garmin for trainer workouts. Integrating a Garmin with my smart workouts is one of the main reasons I purchased the 830 and I can't use that feature as intended. Is this an issue that is being looked at? Is there a fix?
