Is there a reason I haven't got the play store on my watch 3. I need to download on the watch from the play store Google pay but I can't find the play store app?
When you are looking at a particular app on Google Play store, look to the right side of the install button there is a downward pointing arrow if you tap that and select your watch it will install the app to your watch. It will only let you select the watch if the app is compatible with it.
