Installing watch faces on Fenix 6x pro from Android app - newbie question :)

Hi,

I have a Fenix 6X pro Solar (straight out of the box and fully charged). It is linked perfectly to the Garmin Connect App, I also have the Garmin Connect IQ app as well.

My question is - when I search for watch faces to install via the Connect app, it allows me to search for watch faces, however, whenever I select a watch face (or even an app for that matter), I am told if I want to install the latest version of this app, I must update my Fenix in Garmin Express. I have just upgraded the watch to v25. Am I doing something wrong in the app?

Thanks in adavnce

Scott
