How can I not automatically show the score after 9 holes of an 18 hole round

Dont think you can turn that off. 

It only takes a second to press "resume"?

I’d like to be able to disable this feature too.  Seeing my score (especially if good) is distracting.  

Came here to request the same thing - I don't want a score summary if I'm on track to beat my course record.

I agree it is distracting to me also to see my score (so far) while in the middle of playing he 9th hole. takes my mind of the game (could be a result of a weak mind, ha).

You can turn this off on the new S70 but it would appear that Garmin have little interest in updating the software of a watch only one generation old!

That is good news! Not worth buying a new watch that I only use for golf though. :-) Hope the Garmin folks are monitoring these threads and include this function in the next update. They seem to do updates relatively regularly. 

Not as far as I am aware. I am not going to buy the new watch, they clearly have no interest in updating their products. 

This was fixed a few releases ago (maybe a year back) for Fenix watches - I can't speak to the approach series.

The Approach S62 does not have this feature. The Approach S70 received this option, along with the epix Gen 2/fenix 7 series of newer devices.
