I have problem when test in-app purchase sanbox in independent WatchOS application
Enviroment: Xcode 11.5 and WatchOS 6.2.6 - Swift UI project
The problem is when i call function buy the product, the WatchOS (both simulator and real device) alway shows message: unable to purchase app sign in with your apple id from the apple watch app on your iphone.
I tried to build and test in TestFlight mode also, its same result.
Changed AppleID in Iphone (pairing with watch) but its same result too.
When debuging In simulator and device, i can get informations about IAP packages (include price and description) created on the Itune connect
Many thank !
