What you lose when you buy garmin fenix 6?

Hi

I would like to share with my experience with Garmin watches.

Always when I update to new Garmin watch I always lost something like:

1. Training load -  I lost moving from FR945 to f6x.

I have a training load from the fr945 and is not connected with date from Fenix 6x ;-(

If you don't know what value that gave you here is explanation under that link

2. I am a big fan of Garmin watches in my history there is a lot of Garmin watches example:

fēnix® 3
Forerunner® 220
HRM-Run
fēnix® 5
Forerunner® 935
fēnix® 3 Sapphire HR
fēnix® 5X Plus
Forerunner® 945
fēnix 6X - Pro and Sapphire editions

Below example and again lost the name of my all device.
