I originally posted this in the discussion forum, but I should have posted in here in the Bug Reports Forum.
Here's the original post.
I still have users reporting this problem. Here is the most recent.
The problem only occurs on Macs running Garmin Express. On the Sensor Id setting, it pops up a message "This cannot be greater than 0" even though the setting is setup to be a number between 0 and 99999. On the High Alert set point, it pops up a message "This must be between 0 and 0" even though the setting is setup to be a number between 1 and 100.
The problem affects both Apps and Data Fields.
The settings work properly on Express on Windows and in Garmin Connect Mobile.
