Garmin Connect app is no longer showing graps for swim sessions, only average. It is only since this week, it has been working fine for years. I did not change any settings
Works all right for me in Garmin Connect Web (the forum that you are posting to, is for that website). If you refer to the app Garmin Connect Mobile Android, then have a look at this thread in the relevant GCM Android forum: Pool data not displaying in Android App
