It still does not work. I can get IAP price info but when trying to purchase, asks me to login using iPhone. I have an independent watchOS app. I’ve seen people create a skeleton iPhone app this is used for IAP purchasing etc. Apple seem to allow this

in app purchases still not working for independent watchOS app. Keeps asking me to login using iPhone "unable to purchase app sign in with your apple id from the apple watch app on your iphone"
