Treadmill Run Calibration Option Not Available in Latest Updates: No "Calibrate & Save" option after Treadmill run

The SAVE option was displayed, no CALIBRATE AND SAVE, NO CALIBRATE AFTER SAVE.

There should be a green area to SAVE and just below a red area with three dots (. . .)

click on the dots and it will give the option to calibrate

Thats the problem, its not showing, i have the latest OS version.

First are you using the Treadmill exercise selection?

You need to go at least a mile (your 3 km certainly meets this)

When you hit done - what appears under the option to Save (great) in the red area?  If it is only a red area with a trash can with an X - then I am at a loss.  But if it is the three dots - just click on the dots and it gives the option to calibrate.

Have you read the description of this post? There is no 3 dots or any other option to tap than GREEN OR RED . I need garmin to reply. Thanks

Then you will have to contact Garmin directly through Garmin Support.  They do not have much of a presence on these User Forums.
