Unable to install “app” try again later

I recently swapped my iWatch series 3 to 5, I however discovered that some apps on the watch are not fully activated on the screen, upon clicking on it to install, I usually get an error message saying that app can’t be installed right that I should try again later.

Apps like Calculator,Compass,google map and others aren’t installing.

Even going through app store on my watch it’s just rolling. Note that my internet is very fast.

i get notifications and all, but this is just not installing.

solution please
