Calibration altimeter forerunner 645

My forerunner 645 music won't calibrate....I feel calorie count and elevation are way when used run with my phone and not a garmin watch...

My friend has no problem calibrating his 645 music....we run together and stats are different....

I have the same issue. No matter how many times I try and calibrate, the numbers are way off for elevation, even right after calibrating. I havent looked too much into it as I will probably jump on the Fenix 7s when its launched but you might want to contact Garmin support and see if they have a better answer.
