It seems like the latest version of Garmin Connect (4.58.2 ) is showing contributed FIT fields in the activity summary with precision of zero.
I have a screenshot of an activity summary back on Aug 17/2022 with values saved with precisions of 1 and 2 decimal points. Today, the same screen for that activity shows values rounded to integers with 4/5 rounding. In the connect.garmin.com web portal, the values are shown to 3 decimal point precision (not what is specified in the fit contributor xml file but OK.
Can anyone confirm this problem?
