How do I find the Endurance score on my Garmin Fenix 6X Sapphire?

You can't, since Fenix 6 does not support this feature:

For hours i have looked for an overview of what is supported and what is not supported by my Fenix 6X Sapphire. Where would i find that? 

Also, do why isthe feature not supported? 

But that is ridiculous? I thought i had bought myself a premium watch capable of the newest data analyzis in fitness.

And you have all the premium features that are in its specifications, and that you paid for. I do not think that any smartwatch manufacturer promisses to upgrade all their devices eternally with features developed for new models.

That is such bad manner! Turns out, I am not the only person who believes this is bad - Watch reddit on r/garmin - I've cancelled my Instinct 3 Solar order. The thread is filled with customers feeling the same. Never getting a Garmin again.

Given that you are complaining that you are not getting a new fitness score on, what, a 4+ year old model, it doesn't sound like you were 'getting a Garmin again' anytime soon. Let's be honest.
