Good afternoon Garmin technical support,
Why did you remove the Soccerscoreboard app?
And does App returns again ?
I'm sad too this app is not available anymore. I still have it on my watch - and use it every time. Other apps don't fit the bill for several reasons.
Hopefully the app gets reinstated on the IQ store! Or maybe someone feels inclined to make the app again from scratch...
Here's all the info I have on the app, for prosperity!
