I may have found a bug tonight. Swam for ~36min then accidentally paused the workout, followed by a quick resume (total swim time of 52 min). Didn't notice anything weird on the watch, but when it synced with Garmin Connect, I get the correct distance, but the workout time is only for the first segment (pre- accidental pausing). This results in the pace being wrong - in this case, VERY wrong as it shows as 2:46:40 min / 100 m. The stroke count is correct, but the total moving time is showing as 75:13:51.
I don't know of any way to correct this, short of deleting the activity and adding a manual one.
Anyone seen something like this before?
